Yanmar 4LV Diesel Engines

Yanmar, one of the world’s leading manufacturers of advanced marine diesel engines, has introduced its new series of common-rail (CR) engines.

The new 4LV series offers a range of 5 engines with outputs from 150 to 250 mhp which harness the very latest in electronically managed CR fuel injection technology for the mid-section of Yanmar’s range of clean and efficient diesels. Yanmar will be introducing the 150, 170, & 195 mhp units. The engines have been specifically designed for the rigours of both sailing yachts over 60′, power recreational boating such as super yacht tenders and small commercial craft applications.

Demonstrating the Yanmar 5x best-in-class features reflected throughout its new generation of marine diesel engines, the new 4LV range is clean, interconnective, quiet, powerful and fuel efficient. By exceeding the strict EPA Tier 3 and EU RCD Tier 2 emission regulations, the engines feature virtually smoke and odour free operation.

For direct connectivity, the 4LV range has been developed alongside Yanmar’s industry leading electronic control and monitoring systems and connects seamlessly with NMEA or J1939 networking. This ensures support of advancing marine technologies and allows future-proofed integration to any multifunction bridge display.

The engines incorporate the latest technology to enable very low vibration and noise levels for a smooth and quiet running engine. These include a chain rather than belt drive, a counterbalance shaft and refined component design.

Featuring a class-leading power-to-weight ratio, the 4LV delivers a powerful low-end torque performance due to the 2.8 L displacement. This results in a stunning acceleration and set these engines apart from others in their power range.

The digital control systems constantly monitor the engine to maximize performance and minimize fuel consumption, ensuring these are among the most fuel-efficient engines on the market.

Extremely versatile, the 4LV is an ideal installation for sailboats, motor boats, or light commercial vessels. Furthermore, the range will be complemented by a choice of Yanmar controls, which include the VC10 electronic control panel, bringing real time diagnostics, and the JC20 joystick system, providing innovative manoeuvring solutions.

Floris Lettinga, Global Sales Manager at Yanmar Marine International, said: “These engines have been designed for an important segment of the boat propulsion market where globally there is intense competition from many players. With our technical skills at the cutting edge of diesel engineering, exemplified by these latest additions to our comprehensive CR engine offering, Yanmar is now the only marine engine manufacturer to offer a full range of CR engines from 40 mhp right up to 440 mhp, all with low emissions, lively performance, superb fuel efficiency and renowned Yanmar reliability.”

The 150, 170, & 195 mhp 4LV engines will be available as inboard models from autumn 2017 , The 230 & 250 mhp inboard models and sterndrive models make their introductions in early 2018.
