Fuel in the D4D is pressurised to an extremely high 135mpa within the "common rail" that feeds all four cylinders (older diesel engines have a separate pipe leading from the pump to each cylinder). The high pressure injection creates better fuel atomisation for complete burning and increased power output. And because there is less fuel wasted through inefficient combustion, the D4D delivers better fuel economy too. 3, record 1, English, - high%20pressure%20common%20rail

A common rail engine is designed to supply constant fuel pressure to electronically controlled injectors through a shared fuel reservoir. This means that the fuel supply is not dependent on the engine revs. A common rail system is built around four basic components : a high pressure pump with pressure regulator and inlet metering valve, a rail which contains a pressurised reserve of fuel, injectors which inject precise amounts of fuel into the combustion chamber as required and a Diesel Control Unit-the ’brain’ of the system, which precisely controls injector flow and timing as well as rail pressure while continuously monitoring the operating conditions of the engine. 4, record 1, English, - high%20pressure%20common%20rail

Le secret de la «rampe commune», c'est son tube interposé entre la pompe d'injection et les injecteurs. Alors que dans un système d'injection directe classique, la pression dépend du régime-moteur, cette rampe commune, d'un volume de quelques centimètres cubes, va jouer le rôle de réserve de pression. Ainsi, quel que soit le régime-moteur, le moteur dispose d'une pression pouvant atteindre 1500 bars. 3, record 1, French, - rampe%20commune%20%C3%A0%20haute%20pression

The Ausroc 3(A3) launch vehicle has a liquid fuelled motor that burns JA-1 kerosene with liquid oxygen, and uses regenerative cooling. The motor produces 35 kN at sea level and has a burn time of 80 seconds. The motor is gimballed to facilitate pitch and yaw control. The wall of the combustion chamber, throat and expansion nozzle consists of 102 stainless steel tubes stacked side by side running parallel to the motor axis. The tubes will be brazed together and the assembly wrapped in a carbon fibre composite. The composite wrapping is used to relieve to tubes of the hoop stress generated by the combustion pressure(2 MPa), whilst the tubes contain the combustion heat(3500 K). The top end of the motor has a kerosene inlet manifolt, oxygen dome and injector block. The kerosene inlet manifold delivers kerosene to every second motor tube, where it travels down to the arse end of the motor. Here it enters the lower kerosene manifold which is a simple plenum ring. This allows the kerosene to flow into the other alternate tubes which deliver it back up to the inlet manifold. The inlet manifold then directs the kerosene to the injector block, which sprays it and the liquid oxygen into the combustion chamber. 2, record 2, English, - liquid%20fuelled%20motor
