LRT Engine design utilizes …

“It`s not the Internal Combustion Engine we have to ban, it`s the fossil fuels.”

The statement is not ours even if we wanted to. Electric cars have been pointed out by many as a solution, but there are good reasons to say that it will not be for large parts of the world’s population.

Battery electric cars (BEV) have two significant challenges in use, time for recharging and the weight of the battery. Weight is an important factor for increased energy consumption and long range must be paid for with increased energy consumption through larger battery packs. On the whole, a spiral that does not seem very sustainable all the time, the lack of a simple raw material for battery production appears to be more and more intrusive. In addition, the electrical infrastructure is far from adapted to an electric car fleet, even in well-developed countries such as the United States.

Many players are pointing towards e-Fuels as a viable solution. LRT engine architecture is well suited to meet this development through its ability to adjust the engine’s compression ratio to the type of fuel that will be available in the future while being able to utilize today’s fuel qualities.

Need for innovation

Traditional combustion engines are under pressure and emissions is the main reason. One of the main drivers in engine design is downsizing witout compromising its performance to ensure significant fuel savings. An other trend is the shift against zero CO2 fuels to minimize the GHG footprint.

LRT engine architecture has obvious advantages in both trends. Through extremely compact design and low weight, you achieve a weight / performance that is industry-leading. We have built a prototype that provides about 200 HP with a weight of about 104 kg without optimization for industrial production. The cylinder volume is a modest 1.2 liters.

Through a radical solution for geometrically changing the compression conditions in the engine, fuel consumption is significantly improved under normal operating conditions for a car. Based on its experience from the VC-T engine, Nissan claims that the savings are about 27% in “normal use”.

Geometric change in compression ratios also allows the engines to be less “vulnerable” to fuel properties such as calorific values ​​and octane numbers. This gives the concept of Multifuel new content. In principle, the LRT engine can fill regular petrol one day and 100% e-methanol the next day without the need for mechanical changes. In short, well prepared for today’s and tomorrow’s fuel. Wherever you are on the planet.
