4 Cylinder Petrol Engine.
4 Cylinder Petrol Engine
In conjunction with the brake
unit, the test engine makes up a complete engine test stand. The engine
is a 4-cylinder in-line engine with a regulated catalytic converter. It
has an integral closed cooling water circuit.
A solid, welded
base frame on rollers carries the entire setup. Hazardous areas such as
hot surfaces and rotating parts are covered with perforated plates. The
engine is connected to the brake unit using an elastic coupling with a
jointed shaft. The test engine is attached to the brake unit using
toggle-type fasteners.
The engine is fitted with sensors that
measure the temperatures and the cooling water flow rate. The control
cabinet contains all of the electronic equipment for managing the engine
(factory set). On the control cabinet are an ignition key, an operating
time counter and warning lamps. Data is transmitted between the brake
unit and the engine via a data cable connecting the control cabinets for
the two units.
For safety reasons, the engine has been adjusted
so that it is only possible to start it when it is connected to the
brake unit both mechanically and electrically.
