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.
The design is a four-cylinder, two-stroke, piston diesel engine, in an inverted-V configuration, with turbocharging and supercharging, mechanical fuel injection, liquid cooling, direct drive. It can run on Jet-A or sustainable aviation fuel. The manufacturer claims that it has "40 percent fewer moving parts than other engines in its category ...
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 ...
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).
1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).
Schematic animation of a two-stroke uniflow diesel engine The engine is a uniflow design with four poppet -type exhaust valves in the cylinder head. For maintenance, a power assembly , consisting of a cylinder head, cylinder liner, piston, piston carrier, and piston rod, can be individually and relatively easily and quickly replaced.
All models of the Dash 7 Series are powered by a 12-cylinder or 16-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine carried over from the Universal Series, and have speed-based adhesion control with a multi-channel LED annunciator panel. Dash 7 Series traction motors are powered by direct current.
Like that earlier Series, it has a microprocessor-equipped engine control unit, and a modular system of construction of the vehicle body. All models of the Dash 9 Series are powered by a 16-cylinder, turbocharged, GE 7FDL 4-stroke diesel engine, with electronic fuel injection and split cooling.
