Horse Technologies, a division of Horse Powertrain, has begun production of its all-new HR12 LPG engine. This is a global first as it combines direct injection technology with LPG fuel.
The 1.2-litre, 3-cylinder turbocharged unit is the latest powertrain in Horse’s growing lineup of hybrid and combustion systems. Alongside its use of direct injection for LPG, the HR12 LPG features a 48V mild hybrid system that includes a Belt-integrated Starter Generator and a DC/DC converter. This setup provides electric boost during acceleration, supports start-stop functionality, and helps reduce both fuel consumption and CO₂ emissions.
With a peak output of 140PS (103kW) at 5,500rpm and 230Nm of torque from just 2,100rpm, the engine looks to be strong in terms of efficiency and everyday usability. Running on LPG delivers a 9% reduction in CO₂ emissions compared to petrol, and the powertrain meets current Euro 6e regulations with a roadmap to comply with upcoming Euro 7 standards.
Key to the system is a specially developed direct injection setup tailored for LPG use, complete with an electronic vaporiser for improved compression control and strengthened valve-train components. Despite the addition of LPG hardware, practicality remains intact, thanks to a fuel tank that fits into the spare wheel well without compromising interior space.
“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”.
Patrice Haettel, CEO of Horse Technologies
The HR12 LPG is the seventh powertrain generation produced at the Mioveni facility in Romania, which has an annual capacity of 450,000 engines. Development was led by Horse engineering teams across Bucuresti, Titu, and Mioveni.
