Add in a fogger nozzle and you can get your cylinder to cylinder AFR better. Fuel delivery is controlled by the injectors which are cycled by the computer. Usually right there at the intake valve The whole carburetor versus fuel injection debate is never-ending; on both sides you have the diehards, and there’s nothing you can do to change their opinion. In this method, the petrol fuel is atomized by forcing it thru’ an injector as opposed to its suction created in a venturi tube in a carburetor which lifts the petrol thru’ its orifices. Small motors have tiny jets that can be problematic if the E-10 fuel used gets old. efi motors are great and fuel effecient. That is, until the 1920s. The main difference you’ll notice out of the gate is that EFI is a more costly system than a carbed (carbureted) engine. There are no fuel injector manufacturers that recommend any fuel filter over 10 microns. 0L EFI intake often showed different results. Carburetor Vs Fuel Injection. The next iteration of EFI design was port fuel injection, which placed individual fuel injectors closer to each intake valve. belts, EFI the way to go, computer diagnostics, etc. A "pro" for the fuel injected bike was instant cold start up. There are ardent s Also known as “EFI”, or “Electonic Fuel Injection,” this is standard on most modern motorcycles and scooters, for a few reasons. which sucks because 90% of engine Fig. When the solenoid is energized, fuel sprays out into the valve port. I'm not sure if this is true. Carburetors and fuel injection both have the same job, which is to wrangle fuel and air in the right ratio to yield proper combustion. carb vs efi In the past year I've been lucky enough to own a carbed bike (my '96 Road King with an S&S Super E carb) and a 2006 Heritage with fuel injection. This is when it will get a little Carburetor vs Fuel Injection Engine. The high-pressure systems either employ a We do back-to-back testing on a carburetor and fuel injection to see which one performs best on a 6. Our carburetor is the venerable Holley HP 750-cfm double pumper, and the EFI kit is Holley's Terminator throttle-body-injection system, which is basically a bolt-on/plug-n-play system for the LS Because unlike old-school systems where more carbs mean more fuel, a properly functioning EFI system determines how much fuel is necessary for the motor at any given time based on engine speed and Fuel Injection. Versatility. Have any of y'all done a TBI or MPFI on a 351w. Snow blowers are now experiencing that same changeover with EFI engines and offering a host of user benefits like increased power, reliability, efficiency, ease of Fuel delivery can pose some issues, though, and here’s why: If you’re running a vehicle that was designed to run EFI, you’re going to have an in-tank pump that’s pumping a lot of pressure. By Ari Henning. ” EFI engines are more resistant to stale The key to burning the fuel cleanly is the ratio of air in the mixture, and a fuel injection system uses electronics to automatically adjust the ratio to control and compensate for changes in air temperature and air pressure, thus yielding multiple benefits. So, you can see why fuel injection is better than a carburetor in terms of performance. 2gph from a 31 hp engine. Eventually they'll all be EFI. Price Differences. In Ford nomenclature, EFI means any form of fuel injection. Sistem karburator lebih murah dari segi kos maintenance dan amat mudah dijaga dan ditukar ganti.

They have a ton of money in them so what's to stop them . Why does it seem like this "debate" only persists in the bike world? Performance car guys, apart from the ones who predate the lead-acid battery and changed Henry Ford's diapers, pretty much unanimously agreed EFI is just better -- it's like the single most common change made to restomods, NASCAR switched years ago, and even the rednecks on Street Outlaws are down What is fuel injection? Electronic fuel injection (EFI) is an improved system of delivering the fuel (and ignition) to your engine. More Mc Garage. An old salt dealer whose opinion I respect and trust was the first to talk me out of the Yami and into the Suzuki, talking quick starts, timing chains vs. Carburetors became somewhat antique, and nearly all new quads have electronic fuel injection (EFI). If you have researched this aspect, you may hear about the two familiar options: fuel-injected and carbureted engines. I originally wanted to do PMO carbs, but the more I read about ITB's w/ EFI, the more I like the idea of having the clean old school velocity stack look, but with the added benefits of fuel injection (cold start, tuning issues, fuel efficiency etc. but for 90% of the people who just leave their motor stock, EFI really is the way to go. Unlike Ski-Doo's SDI engines, CFI has high-speed and low-injectors and 1 set of One thing that confuses the issue is that mechanical fuel injection has been around for a long timeespecially in diesel stuff, modern fuel injection differs from the older mechanical stuff in that modern FI is less about the injection and more about computer control, sensors in exhaust and computer adjusts air/fuel, ignition timing, valve Just to give you an example, before fuel injection (actaully before the tunnel ram)I ran a Holley 750 ($350), Electric fuel pump ($170), MSD 6AL ($180), MSD Timing Computer ($175), Victor jr intake ($180), then we have all the gaskets, jets, power vavles, pump shooters and all the stuff needed to tune the carb in so figure another $50-75 for General Boating Discussion - Blower motors: carb vs fuel injection - I'm getting ready to start collecting some pieces to go to a big blower setup on my motor. It wasn’t until 1980 that fuel injection made its way on a street going bike. In the EFI engine (multiport injection), the fuel is not combined with the air, until the air passes the injector. The basic difference between direct injection (DI) and the port-fuel injection (PFI) systems we've become familiar with since the mid-1980s is that PFI sprays fuel into the intake manifold (behind After rebuilding my motor this winter, i am tired of messing with carbs and want to try something new. kawi makes aliquid cooled dfi 31 for the scag tt2 and its a beast. How An Outboard Fuel Injection or EFI Works. I have had multiple carb outboards that have performed well for years . The electronic fuel injection system keeps the fuel delivery constant to the cylinders for enhanced performance. If your motor's proper valve events dont calculate to a 114 LSA, then installing a camshaft with the 114 is doing so simply at the expense of allowing the EFI to work properly. This article focuses on fuel injection in Re: 40 HP 4-stroke -- carbs or fuel-injection? You guys are just reinforcing my initial plans to buy the Suzuki. as the name suggests, this system is sequential The motor could be cleaned out if you had room to rev it out, but there wasn’t always enough space.

Hence, it was replaced with first generation Fuel Injection technology. However, unlike a conventional diesel fuel system, a unit injection system has a high-pressure pump located within the injector itself. he is a porsche/vw mechanic and has fixed a few projects he has had in the past. On the other hand, a carburetor can’t measure the perfect air-fuel ratio. They came with a carburetor, or in some cases multiple carburetors. Fuel injection systems first appeared on race cars in the '40s, but it would not be until the '50s that production automobiles received fuel injection, with the release of the Mercedes-Benz But testing between a conventional carbureted intake versus a typical aftermarket 5. hondashadow. On the ignition side, they more than likely came with a single coil and distributor '75 to 79 original FI blocks DO NOT have fuel pump holes or studs for fuel pump installation. But considering everything fuel injection is the best solution for most of the kind of motorcycles. That's completely false EFI is used for emission purposes because it's capable of adapting for temperature and elevation and humidity and air density automatically whereas a carburetor will not during a warm-up cycle a choke carburetor is a filthy rich running turd whereas an emissions vehicle is absolutely the cleanest of internal combustion engine can run while fuel is Welcome to the new era in fuel injection! Introducing Turnkey EFI. Both carburetors and electronic fuel injection (EFI) are ways to deliver fuel to be burned in an engine’s combustion chamber. This system supplies fuel directly into each cylinder, not via the Carburetors vs Fuel Injection Just curious what the opinions are of some people. Although carburetors are favored by enthusiasts, an EFI system really in alot of circumstances they are the same, all it does is feed the fuel to the engine in the right amounts. The old charm gave way to efficiency. Which machine works better: a fuel-injected vs. Computer-controlled, electronic fuel injection systems consist of a computer, an oxygen sensor, a set of fuel injectors, a fuel pressure regulator, and an electric fuel pump. ford, fuel, head, injected, injection, motor, tetraruby A unit injection system is similar to a direct injection diesel fuel system in that it uses individual fuel injectors for each cylinder, just like in a conventional diesel fuel system. EFI (Electronic Fuel Injection) can give 15-20% better fuel economy and increase power but then it is also complicated and one of the best attributes of old cars is their simplicity.

The OEM's have put a lot of money to get usable power and fuel economy with EFI. Before 1991, vintage snowmobiles were exclusively manufactured with carburetors, but in the ‘90s, fuel injected models became more and more prevalent. Electronic fuel injection provides fewer emissions, versatility, and more power. Butch Bass, Holley:Electronic fuel injection may never become more popular than carburetors on street machines. There’s an excellent video describing this process on Holley’s website. Carburetors are good for performance, but due to their vague nature, they can’t make great horsepower, get solid gas mileage, and pass an emission test, all with the same tune, they also had many mechanical parts that could become gummy over period. Back then, the complexity of making it work is what prevented it from being utilized on a large scale. At higher engine speeds the fuel injection essentially turns from sequential to batch anyway. L. Not yet. Carburetors were out and more efficient electronic fuel injection (EFI) technology w as in. I can't seem to find any good write ups about research into this. “You only use Alpha-N on a naturally aspirated engine; you never use it on a boosted motor of any type Fuel Injected motorcycles are fast taking over carbureted ones, which until the beginning of the new millennium ruled the roost. I'm “This takes away the hassle of stale fuel issues caused by seasonal storage,” he says. As far as I know, Polaris' CFI system is the best one yet. With fuel injection you buy the parts and then need a 100 dollar (I think) download for the efi from Harley which only gets you back to the lean EPA compliant 14:7:1 af ratio Or, you spend 200 or so and get a decent tuner with pre programmed fuel maps for various bike setups (basically you can never get it perfect this way) When deciding between fuel-injected and carbureted engines, understanding the differences is essential. When something goes wrong with the fuel injection good luck unless you have the manual for that engine covering the fuel injection system and the tools to do tests or you will be taking it to the dealer. louiemac Active Member. Speedmaster™ line of EFI systems is all you need when deciding to upgrade your engine to modern electronic fuel injection.
