The Design and Development of The TN Series Diesel Engine

In the small engine market, it is essential that engines should be competitive in price, fuel-efficient, reliable and durable. This is nowhere truer than for units in the horsepower range below 100kW.

With these goals in mind, recent trends in engine development have focussed on increased power with a smaller swept volume at high speeds.

The development of this new series was vitalized by intense competition in the industrial engine market, especially from automakers, and a trend which is particularly noticeable in the United States towards the replacement of gasoline drive with diesel in the range below 50kW.

One result is that engine design and manufacture have become increasingly complex and demanding. The TN series is designed to meet these new standards and ride the growing trend towards dieselization. It replaces the current TL and THL engine series.
