Tuned Port Injection in General Motors Vehicles

General car tuning port injection In 1985, General Motors' vehicle first produced a production tuning port injection system (TPI). GMs built using these systems are Corvette, Pontiac Firebird, Pontiac Trans AM and Chevrolet Camaro. At the time of installation, these systems are up to 35% more powerful than carburetor systems and have up to 20% more horsepower, torque and economy than available fuel injection. 1985 - 1988 TPI system uses the following sensors and equipment to control the engine: mass air flow sensor and module, manifold air temperature sensor, cooling water temperature sensor, oxygen sensor, throttle position sensor, cold start

From 1992 to 1996, GM introduced a system called Central Port Injection or Central Port Fuel Injection. In this system, instead of the central throttle body, fuel is injected into each inlet using a tube with a poppet valve from the central injector. Fuel pressure is similar to single point injection system. CPFI (used from 1992 to 1995) is a batch fire system and CSFI (since 1996) is a sequential system. Multi-point fuel injection (also called PFI, port fuel injection) injects fuel to the intake port immediately upstream of the intake valve of each cylinder, not the center point in the intake manifold. The MPI system is a sequential method in which the injection timing coincides with the intake stroke of each cylinder, mass production in which the fuel packet is injected into the cylinder without being exactly synchronized with the intake stroke of a specific cylinder, or at the same time when the fuel is injected is there. To all cylinders

There are two general versions of fuel injection, port fuel injection and direct injection. Port fuel injection is commonly used and direct fuel injection is one of the latest fuel injection systems. The direct injection system is designed for 4 or 2 stroke engines. The main advantage of using direct injection in motorcycles is that it can be injected into cylinders based on the load capacity of the engine after completely releasing fuel and air. As the number of manufacturers using fuel injection systems continues to increase, the growth of the fuel injection market will occur in the Asia-Pacific region as these whole systems have better performance. Some of the major improvements in fuel injection systems include better fuel economy, improved throttle response and less emissions. These factors are increasingly important in the current situation and will be a major selling point in the market.
