A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.
On 22 August 2006, after being re-fitted with 750 brake horsepower (560 kW) 'LSR' versions of the JCB444 engines, [2] the JCB Dieselmax car broke the official FIA diesel engine land speed record, attaining a speed of 328.767 mph (529.099 km/h). 24 hours later the JCB Dieselmax car broke its own record, achieving a speed of 350.092 mph (563.418 ...
The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil . Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes , and produces 80.08 megawatts .
The Graflight V-8 is a liquid-cooled, flat V-8 with steel pistons and compacted graphite iron crankcase for better strength and durability than aluminum at similar weight, increasing time between overhauls to 3,000 hours. It is managed by a Bosch ECU and can run on Jet A, JP-8 or straight diesel fuel.
Diesel engines have the lowest specific fuel consumption of any large internal combustion engine employing a single cycle, 0.26 lb/hp·h (0.16 kg/kWh) for very large marine engines (combined cycle power plants are more efficient, but employ two engines rather than one).
Motorsport engines often run on high-octane petrol and can therefore use higher compression ratios. For example, motorcycle racing engines can use compression ratios as high as 14.7:1, and it is common to find motorcycles with compression ratios above 12.0:1 designed for 95 or higher octane fuel.
The thrust-to-weight ratio is usually calculated from initial gross weight at sea level on earth [6] and is sometimes called thrust-to-Earth-weight ratio. [7] The thrust-to-Earth-weight ratio of a rocket or rocket-propelled vehicle is an indicator of its acceleration expressed in multiples of earth's gravitational acceleration, g 0 .
The prime-mover is a GE Evolution Series 12 cylinder turbocharged internal combustion diesel engine which produces 4,500 horsepower and transmits 4,261 HP to the wheels through six traction motors, one on each axle (Co'Co' configuration).
