Stoichiometric combustion runs at a 12:1 compression ratio and is quieter than the the 17:1 ratio of the diesel cycle.

To achieve higher efficiencies, new thermodynamic cycle concepts beyond the Diesel cycle are needed and have been highlighted by several roadmaps, such as those published by the UK Autocouncil [2].

The use of biogas in diesel cycle engines is achieved by using two technologies: the conversion from diesel to Otto cycle and bi-fuel conversion (diesel and biogas).
Currently, the Diesel cycle engine manufacturers for the agricultural sector frequently use supercharging by turbocharger to obtain higher power.
The heat energy source is generated external to the Stirling engine rather than by internal combustion as with the Otto cycle or Diesel cycle engines.
From a thermodynamics point of view, the Pure Burn engine cycle is a textbook 'constant volume engine cycle', which is more efficient than the constant pressure diesel cycle. A proportion of post-combustion gases remain behind in the combustion chamber to act as a natural catalyst for the next cycle-this is naturally occurring exhaust gas recirculation (EGR).
Excluded from this rule are those motor vehicles: a) Powered by compression ignition or diesel cycle engines."
This joint venture development uses liquid natural gas as its fuel but unlike other LNG heavy-duty applications, the Cummins Westport is a diesel cycle where a mixture of 5 percent diesel fuel and 95 percent gas is injected into the cylinder.
In the industry, engine manufacturers from different sectors have already mastered the use of biodiesel in diesel cycle engines, allowing its complete or partial use as fuel.
