Product – Fuel Injection System

HP EngineTransonic Combustion has developed a fuel injection system which allows the combustion of different fuels from ambient temperatures to supercritical states in a controlled manner.

The Transonic Combustion System is comprised of Fuel Injectors, a Fuel Heater, a Fuel Rail and a Fuel Pump.

A fuel pump feeds fuel into the injectors via a fuel rail. Prior to entering the injectors, the fuel is preheated by a fuel heater. The injectors attached to the fuel rail meter, atomize and provide further temperature adjustments in order to precisely meet the operational demands and ensure the best possible mixture formation for the engine.

Fuel Injector

Fuel InjectorIn modern engines with Direct Injection, the Air / Fuel mixture is formed directly in the combustion chamber. During the intake stroke, only combustion air is drawn through the open intake valve. Fuel is then injected directly into the combustion chamber. The difference between current DI systems and the Transonic Combustion System is the injection of heated fuel. The Transonic Combustion Fuel Injector adds heating capabilities to the usual precise metering, preparation and distribution of the injected fuel. Fuel heating is the enabler for reducing fuel-consumption and emission levels.

Fuel Heater

Fuel HeaterTransonic Combustion’s fuel injection system is unique in that it delivers heated fuel to the combustion chamber. The primary function of the Fuel Heater is to pre-heat the fuel prior to entry into the Fuel Injector, utilizing waste exhaust heat. This minimizes or eliminates the load on the vehicle electrical system.

Fuel Rail

Fuel RailThe Fuel Rail is designed to evenly distribute the heated fuel to the injectors while minimizing heat loss.

Fuel Pump

Fuel PumpThe Transonic Combustion System utilizes existing Gasoline Direct Injection Fuel Pumps, thereby reducing the need (and associated costs) for more expensive high pressure fuel pumps.
