The Ramjet is a continuous-flow port-injection system. Unlike later fuel injection systems that used electronics, this one is based on purely mechanical principles. The two main sub-assemblies of the system are the air meter and the fuel meter. The air meter measures airflow into the engine and manages thermostatic warmup enrichment, fuel ...
An animated cut away diagram of a typical fuel injector. Fuel injectors are used to spray controlled amounts fuel into an internal combustion engine. A solenoid is activated when fuel is intended to be delivered to the engine causing the plunger to become pulled toward the solenoid by magnetic force. This uncovers the valve opening allowing ...
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.
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 ...
Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic multi-point injection system for internal combustion engines. It has been available since the early 1980s. This system has been used in motorcycles, automobiles, and outboard motors.
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.
The injection pressure is 1,350 bar (19,600 psi) [2] in the non TÜ engine, whilst all other engines use a pressure of 1,600 bar (23,000 psi). [2] For fuel injection, magnetic injectors are used, except from the TÜ2 OL and TOP engines, which make use of piezo injectors. [ 2 ]
