Fuel weight will affect the performance of the car, so fuel economy (thus efficiency) is a competitive advantage. Ways to increase power include: Increasing the engine displacement by one or both of two methods: " boring " - increasing the diameter of the cylinders and pistons , or by "stroking" - using a crankshaft with a greater throw.
As the name implies, VLIM/VIM/VIS can vary the length of the intake tract in order to optimise power and torque across the range of engine speed operation, as well as to help provide better fuel efficiency. This effect is often achieved by having two separate intake ports, each controlled by a valve, that open two different manifolds – one ...
This is due to the turbocharger or supercharger already having compressed the air before it enters the cylinders. Engines using port fuel-injection typically run lower boost pressures and/or compression ratios than direct injected engines because port fuel injection causes the air–fuel mixture to be heated together, leading to detonation ...
Early Lucas electronic diesel unit injector. A unit injector (UI) is a high-pressure integrated direct fuel injection system for diesel engines, combining the injector nozzle and the injection pump in a single component. The plunger pump used is usually driven by a shared camshaft. In a unit injector, the device is typically lubricated and ...
In this way, precise fuel injection metering is still retained at all engine speeds and loads. Australian tuners in comparison, prefer to use the less precise method of MAFless tuning (see 'Disadvantages' section above), requiring the engine computer to use predetermined fueling tables, resulting in less finely tuned injection systems that ...
The term fuel injection is vague and comprises various distinct systems with fundamentally different functional principles. The only thing all fuel injection systems have in common is the absence of carburetion. There are two main functional principles of mixture formation systems for internal combustion engines: internal and external.
A fuel-injected engine may alternatively use a mass airflow sensor (MAF sensor) to detect the intake airflow. A typical naturally aspirated engine configuration employs one or the other, whereas forced induction engines typically use both; a MAF sensor on the Cold Air Intake leading to the turbo and a MAP sensor on the intake tract post- turbo ...
Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.
