Typically, hydraulic direct injection systems spray fuel into the air inside the cylinder or combustion chamber. Direct injection can be achieved with a conventional helix-controlled injection pump, unit injectors, or a sophisticated common-rail injection system. The last is the most common system in modern automotive engines.
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine.
Mechanical fuel injection, 'K' stands for German: "Kontinuierlich", meaning continuous.Commonly called 'Continuous Injection System (CIS) in the USA. K-Jetronic is different from pulsed injection systems in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (73.5 psi).
Gasoline direct injection (GDI), also known as petrol direct injection (PDI), [1] is a mixture formation system for internal combustion engines that run on gasoline (petrol), where fuel is injected into the combustion chamber. This is distinct from manifold injection systems, which inject fuel into the intake manifold (inlet manifold).
It still had an iron block, two-valve pushrod aluminum heads, and full sequential port fuel injection. The LG8 also featured a new intake manifold and numerous changes to improve parts-sharing with the larger-displacement LA1 3400. Emissions were improved with secondary air injection and it earned LEV status. The engine featured a 89 mm (3.5 in ...

The LSD is a direct-injection 1.5 L turbocharged SGE variant, with a 74 mm × 86.6 mm (2.91 in × 3.41 in) bore and stroke for a total capacity of 1,490 cc (1.5 L). Compression ratio is 10.0:1 and uses regular unleaded gasoline. This variant has a higher pressure fuel system than the LYX, increasing to 35 MPa from 20 MPa.
The engine used multi-point common rail sequential fuel injection, with fuel injected indirectly into the lower inlet manifold section just before the cylinder head intake ports. Fuel and air delivery was controlled by a cable operated throttle body , with a potentiometer monitoring throttle position and allowing the Motronic ECU to deliver the ...
