In the United States, the Corporate Average Fuel Economy mandates that vehicles must achieve an average of 34.9mpgUS (6.7L/100km; 41.9mpgimp) compared to the current standard of 25mpgUS (9.4L/100km; 30.0mpgimp). Because Diesel fuels are of low volatility, they can be very hard to start when cold. Some potential solutions to increase fuel efficiency to meet new mandates include firing after the piston is farthest from the crankshaft, known as top dead centre, and applying the Miller cycle. This target may contain magnets, or it may be a toothed wheel. It is by arbitrary convention that in the automotive world one is used for engine revolutions and the other for vehicle speed.

Flatheads are old, ancient, obsolete technology. This lateral flow severely restricts flathead breathing capability, although it does promote what today's high-tech engineers term swirl and tumble, which enhances fuel mixing and combustion. Hello. The most efficient Otto-cycle engines run near 30% thermal efficiency. Many other engineers were trying to solve the problem, with no success.[4]. The higher temperature more effectively evaporates fuels such as gasoline, which increases the efficiency of the compression engine. Provided you have an original bellhousing, you can use available Trans-Dapt adapters to install Ford passenger-car transmissions from the mid '60s to the late '70s behind the '49-'53 flatties. Small-block Chevy valves remain popular, but with reduced-base-circle cams they may be too short to permit proper lash adjustment. Reliefs between the valves and bores are much less pronounced than the old days, only about 0.080-inch deep instead of the old-school 31/416 inch. Strictly, such devices are not tachometers since they do not provide a direct reading of the rotational speed of the disk. Like Otto, it took more than a decade to produce the high-compression engine that could self-ignite fuel sprayed into the cylinder. Keep it under 8.0:1. The engine may "feel better" with 27-30 degrees total timing (as read on the crank), but Baron says "it slows up the flame travel. Solution #3: Airflow restriction can also cause an engine to idle poorly. The direct fuel injector injects gasoline under a very high pressure into the cylinder during the compression stroke, when the piston is closer to the top.[9]. Today, that company is Daimler-Benz. Yes, you can have a classic flathead with modern fuel injection. Normally we'd title this section "Cylinder Heads," but on a flathead, the heads-having neither ports nor valves-only form the combustion-chamber roof. Otto and Cie succeeded in creating a successful atmospheric engine that same year. 2-Stroke Outboard Carburetor Synchronization; 2-Stroke Outboard Carburetor Synchronization In this video I synchronize the carburetors on the Yamaha 20HP outboard.
