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.
[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.
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.
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.
The engine had MPFI (multi-port fuel injection), which gave slightly more power and better fuel economy, and two valves per cylinder. The engine had a bore and stroke of 4 + 1 ⁄ 4 in × 4 in (108.0 mm × 101.6 mm), producing 290 hp (216 kW) at 4000 rpm and 410 lb⋅ft (556 N⋅m) at 3200 rpm. It was used by Mercury Marine, named the ...
It is dependent on several factors including engine efficiency, transmission design, and tire design. In most countries, using the metric system, fuel economy is stated as "fuel consumption" in liters per 100 kilometers (L/100 km) or kilometers per liter (km/L or kmpl).
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 Cummins L-series engine is a straight-six diesel engine designed and produced by Cummins. It displaces 8.9 litres (543.1 cu in ), and began production in 1982 as the L10 at the Jamestown Engine Plant in Jamestown, New York .
