Combustion Engines offer significant advantages over external combustion
in many applications, particularly automotive where there is a need for
rapid variation in power output, which can be achieved by changing the
fuel supply rate.
However, for continuous operation with extended
service intervals, as required for domestic heating systems, the
challenges facing ICE are formidable; until recently it was considered
that the cost of the components required to achieve the appropriate emissions
efficiency and reliability parameters would be excessive. Early products, based on automotive ICE
technology, operated with some success in niche applications, but were unable to overcome these technical challenges and
with high service and operating costs.
The products mentioned
below, however, have primarily been developed for long life with relatively low service
intervention and incorporate a range of features aimed at achieving the
performance desirable for domestic and small commercial applications.
They are divided into three nominal power ranges, 1kWe, 5kWe and
10kWe matching applications including typical family homes, guest
houses and commercial buildings respectively. Click on the

merits of these engine types see section on
