A diesel cycle engine can be as much as 40% to 50% efficient at converting fuel into work, [2] where a typical automotive gasoline engine's efficiency is about 25% to 30%. [3] [4] In general, an engine is designed to run on a single fuel source and substituting one fuel for another may affect the thermal efficiency.
However, cars registered before this date are taxed based on engine displacement. Cars under 1549 cm 3 qualify for a lower tax rate. [3] In Japan, the engine displacement is one of the factors (along with overall vehicle size and power output) used to determine the vehicle size class and therefore the cost of road tax for the vehicle.
[6] [7] Miles per gallon equivalent cost for alternate fuel can be calculated with a simple conversion to the conventional mpg (miles per gallon, miles/gal). See conversion to MPG by cost below. The MPGe metric was introduced in November 2010 by EPA in the Monroney sticker of the Nissan Leaf electric car and the Chevrolet Volt plug-in hybrid.
Conversions are popular [citation needed] due to a vast aftermarket and many compatible parts between engine versions. Some conversions are very easy; for instance, the supercharged 4A-GZE engine and electronic fuel injection (EFI) system are a direct plug-and-play conversion into a non-SC AW11 MR2. Even the SC-type wiring harness plugs ...
The conversions amongst different types of units, are well known in the art. For the conversion amongst units of energy in the following table, 1 litre of petrol amounts to 34.2 MJ, 1 kWh amounts to 3.6 MJ and 1 kilocalorie amounts to 4184 J. For the car occupation ratio, the value of 1.2 passengers per automobile [13] was considered.
[17] [18] A few years later, the 1961-1964 Ferrari 156 Formula One car used a new V6 engine with a V-angle of 120 degrees and a displacement of 1.5 L (92 cu in). [19] This engine was shorter and lighter than the Ferrari Dino engine, and the simplicity and low center of gravity of the engine was an advantage in racing.
The RB26DETT engine is a 2.6 L (2,568 cc) twin-turbo inline-six engine manufactured by Nissan, for use in the 1989-2002 Nissan Skyline GT-R. The RB26DETT engine block is made from cast iron, while the cylinder head is made from aluminium alloy, which contains DOHC 4 valves per cylinder (24 valves in total) setup
The 1906–1908 Ford Model K luxury car used a 405 cu in (6.6 L) straight-six petrol engine and was the only Ford six-cylinder passenger car engine until the 1940s. The Ford flathead I6 was produced from 1941 until 1951, followed by the Ford OHV I6 overhead valve engine from 1952 through 1964, then the Ford Thriftpower Six overhead valve engine ...
