LPG/CNG Controller ALEX DIESEL

Dual fuel controller for powering diesel engines, using LPG or CNG fuel

The ALEX DIESEL System is based on mixing two fuels: diesel and gas. The controller limits the injection of diesel fuel to an amount that allows self-ignition in the cylinder, and replaces it with a precise dose of gas.

The share of gas in the ALEX DIESEL System is on average up to 30% LPG or 50% CNG. These proportions of additional fuel guarantee proper operation of the engine and the entire system. Adding gas, which acts as a catalyst to the fuel mixture, allows for more efficient combustion of diesel fuel, which is practically impossible in a regular diesel engine.

Diesel engines burn most of the injected diesel fuel, but there is always some portion that turns into exhaust gases (including hydrocarbons, carbon monoxide, nitrogen oxide and carcinogenic particulate matter). In the ALEX DIESEL System, thanks to the improved combustion efficiency of the gas and diesel mixture, emissions of CO2, particulate matter and nitrogen oxides are much lower.

Engine power increased by autogas.

Installing the ALEX DIESEL system increases the torque and engine power. The temperature and exhaust emissions do not exceed the ranges set for the base fuel supply - diesel. Thanks to this, the system does not negatively affect the engine's life and generates economic and ecological benefits.
