The DM33 diesel engines are three-cylinder, four-stroke, in-line, water-cooled engines with direct fuel injection and natural aspiration. They have low fuel consumption. They are easy to handle and maintain and have high reliability and long service life in all climate conditions. Their basic application is for agricultural tractors, but the versions for industrial application, both for steady-state operation and operation with variable loads, have been developed. Last but not least, IMR offers several versions for marine application.
- The engines are produced in standard versions, but at the customerís request some special modifications are possible. The equipment installed is based on the engineís application, installation, working conditions and the arrangement with the customer.
- IMR also provides full engineering of the installation, as well as the after-sales services under warranty period or after it.
- The customer is advised to use standard engine ratings. Still, new ratings can be developed on the customerís specific demands.
