Revetec X4v2 in Trike test day
This characteristic provides strong and instantaneous
acceleration from just above idle. This characteristic
also negates the need to use higher RPM to provide good
acceleration. This also reduces the required RPM range
an engine is normally operated in, further reducing fuel
usage.
We retrofitted the X4v2 engine into a trike supplied by
the Hudson Group. Brad drove the trike for the first
time and right from the start it was apparent that the
engine’s acceleration was impressive. With one person on
the trike, the front wheel lifted off the ground with as
little as 10% throttle opening. After referring to part
throttle dynamometer graphs we determined that we were
utilising around 25kW.
Directors from GTM Trikes visited REVETEC for an on-road
test day. They were only able to throttle on about 25%
which made their vehicle wheel stand until the rear
crash bar was scraping on the road and maintained the
acceleration.
We estimated that we used a maximum 40kW of the engine’s
power. Directors of GTM concluded that using only this
much power out accelerated their 130kW engine at the
same engine speed. They were amazed how this was
possible. They also estimated that the fuel consumption
on the day was around half of their expected usage
compared with their existing engines. |
