TF(M), TS Series (5 – 23hp)

Many Way Tougher, All Ways Superior

Horizontal, water cooled, 4-cycle diesel engines.

• Direct fuel injection produces dynamic power

Combustion power acts directly on the toroidal piston crown, boosting energy, decreasing thermal losses. Extra high output creates the tough torque needed for heavy duty jobs.

• Durability of Yanmar’s direct fuel injection system enhanced by the heat-proof insulator for the fuel injection valve

The fuel injection valve is wrapped in heatproof material. This improve the durability of the valve.

• Bigger displacement gives more in reserve

With their long stroke pistons, they can punch out much greater torque.

• Superior combustion combination direct injection + Bosch pump

The high pressure Bosch pump, the holevalve type injection nozzle, and the toroidal combustion crown add up to the improved combustion formula for better firing and complete burns.

• Delivers the power it promises, right over 40ºC

Another measure of TF’s and TS’s superiority can be taken from its power rating at the ambient temperature, Yanmar rates the hp of the TF and TS while operating at 27°C. This gives the TF110, for example, a rating of 11hp. Other engines, rated at an ambient temperature of only 20°C, specify the same 11hp. But at the 27°C rating they’ll be giving less power than you should expect, while your Yanmar will be delivering 5.5% more! So you know that with a Yanmar you are getting output you can trust, even in ambient temperature over 40°C.

• Significant drop in fuel & lube expenses

The many advantages of direct fuel injection show in direct savings. You’ll be getting the power you want with an economy.

• Dramatic drop in oil consumption

A special separator keeps gear oil and crankcase oil independent, effectively controlling temperature increases. This and other unique features help the TF achieve its remarkably low lube oil consumption.

• Better lube system improves reliability

A crank shaft-coupled throchoid pump circulates lube oil, increasing its life and effectiveness. Oil pressure continuously monitored and corrected automatically. Alarm signals for large pressure drops.
