Gastech's London Taxi Conversion (in conjunction with UK Computer Cab )
In conjunction with Computer Cab UK, we have achieved a standard of performance and emission levels using LPG. this has never before been achieved on a Nissan TD 27 diesel engine. Gastech's approach in this industry has been to convert the diesel engine to dedicated multi port fuelling with lean-burn, spark-ignition combustion. Lean burn offers power and torque equal to the base diesel, with low emissions, low combustion and high efficiency. This technology has been developed by Gastech for the past seven years. We offer both full electronic and manual fuel and ignition systems depending on customer requests, engine type and application.
Gastech Greening for London Black Cabs
The heavy fuel-thirsty world famous London Black Cabs TX1 model is fast becoming ‘London’s Greenest Taxi’. Vehicle life has been significantly extended; EURO III, EURO IV and EURO V emission compliance has been met and surpassed with a Millbrook test confirming the latest EURO standards. Bulk purchasing of LPG will accentuate payback time.
With technology being transferable it will be possible to emulate the London taxi results with buses and HGV’s meeting Low Emission Zone requirements post conversion. An operator with access to LNG (Liquefied Natural Gas) can also confidently expect to achieve lower operating costs and emission levels.

Our Technology in London Cabs Engine Systems
- The Gastech system is one of the most advanced system in introducing gas into an engine.
- The technology is described as "Electronically controlled sequential fuel injection". The system is designed to be demand driven not supply driven.
- This allows the gas system to regulate the input of gas to the needs of the load and conditions of the engine at any one point. Unlike a supply system, that adds gas according to the throttle position.
- The timing of the diesel injectors (known as the 'pulse width signal') is sent to the gas injectors mounted into the common rail "inlet manifold". This allows the gas to be added to each cylinder in time with the piston (suction stroke) giving the maximum efficiency of gas used.
- Diesel ignites by compression only. This is like adding a "spark-plug" per cylinder into the engine. Because the compression ratio of the gas engine is much lower than the original diesel fuelled engine the stresses on the engine are lower making for longer engine life.
- The vehicle drives like a car not a truck.
- Response to throttle pressure is immediate and allows for more efficient use of the gears.
- The resulting fuel efficiency gives increased fuel savings in the region of 15-40% over the diesel engine equivalent.
