TF Series 7-23hp

Yanmar TF Engines


Yanmar’s unique direct fuel injection system gives the TF series engine a number of unprecedented features such as:

  • Excellent combustion efficiency (low fuel consumption)
  • Delivers the Power it promises, right over 40°c
  • Significant drop in Fuel and Lube expenses
  • Easy Operation
  • Simple Servicing
  • Less Vibration
  • Low Noise Level

Dynamic Power

With direct fuel injection, 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. The high pressure Bosch pump, the hole-valve type injection nozzle, and the toroidal combustion crown add up to the improved combustion formula for better firing and complete burns.

Delivers Over 40°C

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 TF120, for example, a rating of 12hp. Other engines, rated at an ambient temperature of only 20°, also specify the same 12hp. 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 and Lube Expenses

The many advantages of direct fuel injection show in direct savings. You’ll be getting the power you want with better 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 crankshaft-coupled trochoid pump circulates lube oil, increasing its life and effectiveness. Oil pressure continuously monitored and corrected automatically. Alarm signals for large pressure drops.

The Complete Diesel Maker

From the basic blocks to the sophisticated fuel systems, Yanmar builds the complete diesel engine. It’s a level of integration few other makers can claim.
