HHO Plus manufactures hydrogen-on-demand generator systems and engine carbon cleaning solutions designed to improve vehicle fuel efficiency and reduce emissions.
HHO Plus, founded in 2008 and based in Portugal, helps drivers convert standard internal combustion engines into more fuel-efficient hybrids using hydrogen technology. The company specializes in Hydrogen-on-Demand (HHO) generator systems that use electrolysis to split water into hydrogen and oxygen. This gas is then introduced into the engine's air intake to improve combustion efficiency, reduce fuel consumption, and lower harmful exhaust emissions.
In addition to complete car, truck, and marine kits, HHO Plus produces essential electronic components such as Pulse Width Modulators (PWM) and EFIE chips to optimize the air/fuel ratio in modern vehicles. They also manufacture professional Engine Carbon Cleaning machines used by workshops to decarbonize engines and restore performance.

The system uses electricity from the vehicle battery to split water into hydrogen and oxygen gases via electrolysis. This gas is fed into the engine intake, helping the fuel burn more completely, increasing power, and reducing emissions.
A Pulse Width Modulator (PWM), such as the CCPWM60A, controls the amperage going to the HHO generator. This prevents the unit from overheating and ensures consistent hydrogen production regardless of electrolyte temperature or concentration.
Yes, when installed correctly. HHO Plus systems produce hydrogen on demand and do not store pressurized gas, reducing fire hazards. However, users should follow all safety precautions in the manual, such as installing the unit away from heat sources and using a proper fuse.
Yes, HHO kits are compatible with diesel, petrol, and LPG engines. Specific models are available for different engine sizes, from small cars to large trucks.
