(1) Engines developed in 1997
Newly developed main engines and auxiliary engines for marine use between January and December, 1997 by Yanmar are roughly as follows. The following two models were developed as the main engines for medium to small fishing boats.
1) 6KY-ET Engine
The engine was developed on the concept of the engine easy to handle, light in weight, and compact in size as the main engine for medium to small fishing boats. In the engine, improvement of the torque characteristics at the medium to low speed, clean exhaust gas, great reduction in fuel consumption, and rapid acceleration were realized by employing the twin turbo and the special combustion system.
The principal particulars and the photo of the general view are indicated in Table 2.4.14-1 and Fig. 2.4.14-1, respectively.
2) 6LX-GT Engine
The 6LX-GT engine was developed as a part of the lightweight, compact and high-output diesel engine GT series as the main engine for medium to small fishing boats. In the engine, the high-pressure injection was realized by employing the Yanmar-original unit injector, stable combustion performance in the range from the low speed to the high speed was obtained through the optimum matching with the combustion chamber.
