TWX LPG Catalysts
3-Way Catalytic Converter
The major harmful emissions from LPG engines are similar to those from other internal combustion engines Carbon Monoxide (CO) Hydrocarbons (HC) Nitrogen Oxides (NOx)
Unlike diesel engines, there are virtually no particulate emissions from LPG engines but there are high levels of NOx, which pose serious health concerns in the work place.
How it Works
The Pyroban Envirosafe TWX LPG Catalyst is a three-way oxidation catalyst, converting dangerous gases NOx, CO and HC ensuring safe exhaust emissions in the working environment.
For the catalyst to operate at peak efficiency (85-95% reduction), the air/fuel ratio needs to be maintained within a specific balance.
This balance can be achieved either through the truck’s engine management system or by the use of a ‘closed loop’ air/fuel ratio control system.
The closed loop system interprets a signal from an oxygen sensor mounted in the exhaust and varies the A/F mixture by activating a Fuel Control Valve (FCV). The FCV varies the vacuum with the regulator to control the amount of fuel entering the engine assuring that the A/F ratio is maintained for the lowest possible emission levels.
