Mercury Marine, Mercury Racing, Tohatsu, Yamaha Marine, Nissan and Evinrude each developed computer-controlled direct-injected two-stroke engines. Each brand boasts a different method of DI. Fuel economy on both direct-injected and four-stroke outboards measures from a 10 percent to 80 percent improvement compared with conventional two-strokes ...
With Mercury Marine outboards typically having smaller displacement per horsepower and better fuel economy than the competition's motors, an ad ran in publications showing a Mercury-powered boat pulling an elephant on a large ski-like platform. The caption simply read "Mercury, pulls an elephant. Runs on peanuts."
The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]
Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port. The cylinder wall is a thin sleeve surrounding the piston head which creates a space for the combustion of fuel and the genesis of mechanical energy.
Most four-stroke straight-five engines use a firing order of 1-2-4-5-3. [citation needed] This firing order results in the minimal primary (crank speed) rocking couple, and is used by the Volvo Modular engine, VW/Audi straight-five engine, General Motors Atlas engine and Honda G engine. Straight-five engines typically have a 72 degree ...
A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occurring at certain times. Compared with a V4 engine or a flat-four engine, a straight-four engine only has one cylinder head, which reduces complexity and production cost.
The 2023 Ford F-150 Raptor R is rated at 10 mpg city, 15 highway, and 13 combined, per the EPA.. The Ford's fuel-economy ratings are awful, but they're almost identical to those for the 702-hp Ram ...
The most efficient reciprocating steam engine design (per stage) was the uniflow engine, but by the time it appeared steam was being displaced by diesel engines, which were even more efficient and had the advantages of requiring less labor (for coal handling and oiling), being a more dense fuel, and displaced less cargo.
