Internal combustion engines
GUNT offers various internal combustion engines with capacities of up to 75kW, including real car engines with a volumetric displacement of up to two litres. Among these engines are four-stroke diesel and petrol engines, petrol engines with variable compression and two-stroke petrol engines.
The series CT 159 offers four different internal combustion engines in the power range up to 2,2 kW: a four-stroke diesel and petrol engine, a petrol engine with adjustable compression ratio and a two-stroke petrol engine.
