The TE-GD4 gas injection controller for the gas-diesel system allows, without making changes to the engine design and fuel system, to convert almost any diesel engine to operate in gas-diesel (dual-fuel) mode: on a mixture of diesel fuel and gas.
Economic effect
The economic effect is achieved by partially replacing diesel fuel with cheaper gas. Due to physical properties, it is impossible for a diesel engine to operate exclusively on gas. The percentage of substitution depends on the type of gas used. In the case of propane-butane, the percentage varies from 20 to 40%. In the case of methane, from 40 to 60%.
Diesel engine type.
The TE-GD4 system can be installed on any type of diesel engine, from engines with a mechanical injection pump to common rail. Also, not only motor vehicle engines can be converted, but also engines of small power plants, sea and river vessels, diesel locomotives, etc.
Gas used
The TE-GD4 system can use any flammable gas. This is propane-butane, methane, liquefied methane, hydrogen, etc. In any case, the engine only operates with a combined consumption of diesel fuel and gas. In this case, the mixture is ignited by the ignition of the diesel. The ratio between the supplied diesel and gas depends on the properties of the gas and the engine operating modes.
Installation and setup
The installation is not much different from the installation of 4th generation gas equipment: a gas supply system is installed on the engine, the necessary sensors are mounted, an injection reducer, gas electromagnetic injectors are installed.
The fuel supply is limited by lowering the readings of the electronic gas pedal.
The setup is fundamentally different from the setup of conventional 4th generation LPG systems and requires additional knowledge from the installer in the field of the operating principle of diesel engines.
There is absolutely no need for dynamometers during setup. The setup is carried out on the go on public roads.
Protection systems
The TE-GD4 system uses two sensors (both included) to protect the engine from unacceptable operating conditions: a knock sensor and an exhaust gas temperature sensor.
Works with all types of diesel engines
Works with propane-butane (LPG) and methane (CNG)
Gas injection using 1-4 injectors
Automatic tuning
Throttle position sensor (TPS) emulator
Exhaust manifold overheating protection
