However, single-point injection does not allow forming very precise mixtures required for modern emission regulations, and is thus deemed an obsolete technology in passenger cars. [1] Single-point injection was used extensively on American-made passenger cars and light trucks during 1980–1995, and in some European cars in the early and mid-1990s.
This system features one centrally positioned fuel injection nozzle. In the US, this kind of single-point injection was marketed as 'throttle body injection' (TBI, by GM), or 'central fuel injection' (CFI, by Ford).
In a manifold injection system, air and fuel are mixed outside the combustion chamber so that a mixture of air and fuel is sucked into the engine. The main types of manifold injections systems are multi-point injection and single-point injection. These systems use either a continuous injection or an intermittent injection design. [16]
The cylinder head is equipped with hydraulic roller camshaft followers to reduce noise. Utilises an ESC Hybrid management system, and a Pierburg 2E3 carburettor or single point fuel injection on later models. Applications 1989–1993 Ford Sierra (Replaced the Ford Pinto engine from 1989 model year onward)
Multi-point fuel injection (MPI) was introduced late in the 138 series to help meet lowered emission requirements in the US. The original MPI system comprised a large cylindrical plenum running parallel to the engine with individual runners to each inlet port and a single throttle controlling air-flow into the plenum.
A single nozzle nitrous system introduces the nitrous or fuel/nitrous mixture via a single injection point. The nozzle is typically placed in the intake pipe/tract after the air filter, prior to the intake manifold and/or throttle body in fuel injected applications, and after the throttle body in carbureted applications.
The FIRE was originally a carbureted engine, and later progressed to single-point injection (SPI), then to multi-point fuel injection (MPI), using sequential multi-port fuel injection (SMPI) today. It is now used in the 750 Formula in a slightly modified state.
The GA engine is a 1.3 to 1.6 L inline-four piston engine from Nissan.It has a cast-iron block and an aluminum head. There are SOHC and DOHC versions, 8, 12, and 16 valve versions, carbureted, single-point, and multi-point injected versions, and versions with variable valve timing (GA16DE).
