Horse Technologies starts production of world’s first engine to mix DI with LPG

Horse Technologies, a division of Horse Powertrain (a joint venture between French carmaker Renault and Chinese Geely), has started production of its 1.2-litre, 3-cylinder HR12 LPG engine at its facility in Mioveni, Romania.

Featuring 48V mild hybrid technology, the engine includes a Belt-integrated Starter Generator and DC/DC converter, which provides transient torque assistance reduce fuel consumption and CO2 emissions by enabling features like start-stop functionality and electric boost for the engine during acceleration.

The HR12 LPG turbo engine is also the world’s first volume production unit to combine direct injection technology for use with Autogas as well as petrol.

The powertrain delivers peak power of 140PS (103kW) at 5,500rpm and peak torque of 230Nm starting from just 2,100rpm. When running on LPG it emits 9% less CO2 than using petrol. Developed for both EU and global markets, the HR12 LPG fully complies with Euro 6e regulations, and is also designed to comply with new Euro7 regulations.

According to Horse Technologies, the HR12 LPG benefits from a bespoke direct injection system that’s been developed specially for Autogas use, an electronic vaporizer provides more accurate compression control, as well as reinforced valve-train components. The LPG tank can be located below the boot floor in the vehicle’s spare wheel well, ensuring there is no compromise in interior packaging and practicality, the company maintains.

Patrice Haettel, CEO of Horse Technologies, commented: “The arrival of the HR12 LPG demonstrates our commitment to delivering genuinely innovative powertrain solutions across all fuel types. Direct-injection technology for LPG fuel makes it a true world-first for Horse Technologies and is further evidence of our global technology leadership as alternative fuels experts.”
