Lots of useful torque available right where it’s needed. The unique proprietary engine control system optimizes the air intake to achieve even greater power and torque than our diesel engines. Careful design has ensured the ideal stoichiometric combustion ratio is achieved to offer peak efficiency.
Designing industrial diesel engines since 1912 has taught us a lot about fitment on the machine, knowledge we’ve applied to our gas engines. Much thought has gone into making this engine as compact as possible without compromising access to maintenance items. What's more the unique air/fuel mixer system offers unrivalled performance which actually exceeds our diesel equivalent.
By perfecting the stoichiometric combustion ratio the ideal blend of fuel and air is achieved, creating an economical yet powerful unit. Over 30 years’ experience of designing gas engines has culminated in a unique intake system which has improved economy by a tenth over existing mixers, without compromising performance. As well as the obvious life-cycle cost benefits, this gives OEMs the option to install a smaller fuel tank without reducing operating hours between refuelling.
