Description and Specification for Lab Tenders
Astra Scientific Four Stroke Four Cylinder Diesel Engines Test Bench.
The Experimental four cylinder diesel engine test stand. The engine used
here is a four-cylinder diesel engine. It has its own closed cooling
water circuit.
A solid welded frame on rollers carries the entire setup. Hazardous
areas such as hot surfaces and rotating parts are covered with
perforated plates. The connection to the brake is made via a
rotationally elastic coupling with a jointed shaft. The engine is
attached to the load unit by fasteners.
The engine is fitted with sensors that measure the temperatures and the
cooling water flow rate. The switch cabinet contains all of the
electronic equipment for managing the engine (factory set). On the
switch cabinet are an ignition key, an operating time counter and
warning lamps. Data is transferred between the load unit and the engine
via a data cable connecting the switch cabinets for the two units. A
starter battery is also housed in the frame.
For safety reasons, the engine has been modified in a way that it only
starts when it is connected to the load unit both mechanically and
electrically.
FEATURES:
• Engine flexibly mounted on mobile frame
• Plotting of torque and power curves
• Determination of specific fuel consumption
• Determination of volumetric efficiency and lambda (fuel-air ratio)
• Energy balances
• Overall engine efficiency
• Closed cooling water circuit
• Switch cabinet with warning lamps (oil pressure, alternator failure), operating time counter and ignition key
