Four-Stroke Petrol Engine w. Variable Compression for CT 159
Technical Description
The air-cooled four-stroke petrol engine has an identical design to the CT 150. It has been modified to allow investigation of different compression ratios (special cylinder head with interchangeable combustion chamber inserts), adjustment of the ignition point and an adjustable spray nozzle. The engine is securely mounted on a base plate with vibration dampers. The plate is fitted in the mounting provided on the CT 159 test stand and bolted into place. A covered V-belt drive is used to connect it to the HM 365 brake unit. The engine contains a sensor for measuring the exhaust gas temperature, which is connected to the CT 159 display and control panel.
Learning Objectives / Experiments
In conjunction with CT 159 test stand and HM 365 brake unit, in addition to the standard basic experiments - Influence of compression ratio, mixture composition and ignition point on engine characteristic curves and exhaust gas temperature
Features
* Test engine for use in CT 159 test stand
