Yanmar Engine Specs

by Steve Johnson

Yanmar is a company that focuses on producing diesel engines, generators, energy systems and marine propulsion engines. The company was established in 1912 in Japan, and started developing small-size diesel engines in 1933. By the 1960s the company expanded to manufacture agricultural equipment, and released its first tractor in 1961. Today, Yanmar products include industrial engines, tractors, marine engines, generators and construction vehicles. Its industrial engines are offered in a variety of types and models.

Minimax Series

The Yanmar Minimax is a compact engine that has low noise and low vibration because of its ladder frame structure. One of its variant, the 3TNM68, is a liquid-cooled, three-cylinder, four-cycle diesel engine. It has a bore and stroke of 68 mm by 72 mm, and has a displacement of .784 liters. It is a naturally aspirated engine, with an indirect injection combustion system. Its net output is rated at 18.9 horsepower at 3,600 rpm. It is equipped with a radiator for its cooling system, and has an electric starting system. The Minimax engines are compliant with the Environmental Protection Agency (EPA) Tier 4 in the U.S., and can be easily installed on lawn and garden equipment, small agricultural machinery and compact generators.

L-V Series

The L-V series engines are compliant with both the EPA and the California Air Resources Board (CARB) emission standards. They're also available with a multiple power take-off (PTO) shaft that comes with either an electric or recoil starting system. The L100V is one its variants. This engine is a 435-cc, air-cooled, four-cycle vertical cylinder diesel engine. It has a bore and stroke of 86 mm and 75 mm respectively, and has 9.1 horsepower at 3,600 rpm. It has an indirect injection combustion system, and is also a naturally aspirated engine. It has three available crankshafts: straight keyed, tapered and threaded. Two starting systems are also available, a recoil type or a recoil/12-V electric combination. An optional cold start aid is also available for its variants using an electric starting system.

TNV General Purpose

The Total New Value (TNV) engine series is compliant with both the European Commission (EC) and EPA emission standards. The TNV series is also designed to run on B20 bio-diesel fuel. It also comes in a wide variety and includes two-cylinder, three-cylinder and four-cylinder engines. The 2TNV70-ASA is one of its two-cylinder models. This model is a water-cooled, four-cycle vertical cylinder diesel engine with a bore and stroke of 70 mm and 74 mm respectively. It is a naturally aspirated engine, with an indirect injection combustion system. It has a displacement of .570 liter, and its rated output is 13.7 horsepower at 3,600 rpm.
