Alchemist is a revolutionary retrofit, Enhanced Combustion technology for diesel engines. Enabling improved driveability and performance. Watch the video below to find out more.



The Fundamentals

A diesel engine works by using the heat generated by compressing air to ignite the fuel at the top of the compression stroke. Due to the high compression of the air, it is impossible to get the air and diesel fuel to mix together completely and burn evenly. The long molecular structure of the diesel chain also encourages the molecules to stick together into large particulates which are difficult to combust.

This problem is exacerbated by the fact that although the diesel fuel ignites quite quickly, it burns quite slowly, meaning that the flame front does not ignite across the combustion chamber in a progressive way. As a result, the diesel at the relatively cooler chamber walls is late starting to burn, and doesn’t finish its combustion until it is travelling down the exhaust pipe.


Introducing Alchemist

Enhanced Combustion is achieved by the introduction of a minuscule amount of secondary, lighter, gaseous fuel, injected via the air inlet ports. This acts as a reagent, altering the chemistry of the combustion process, and creating a more homogeneous air/fuel mix. In this way the secondary fuel is used as an additive, rather than replacing the diesel in the case of substitution technology like dual fuel.

Any secondary gaseous fuel can be used as the reagent, including Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), Liquid Natural Gas (LNG) and Methane. For convenience, the system currently uses LPG. The result is reduced fuel cost, lower emissions and improved performance.
