Low carbon, low emissions engine for automotive, aviation, marine and industrial applications.

 

Compression-ignition Applications

The Covaxe engine design is ideally suited to a wide range of applications which will benefit from significantly reduced fuel consumption and emissions, low vibration, high but smooth torque delivery, low vibration, high power to weight ratio, and a quasi-cylindrical space envelope. The engine is suited to power outputs from 60 to 350 kW. .

Automotive Applications


 
Because of its low carbon, high efficiency credentials, the Covaxe engine is ideally suited to automotive applications, especially to medium and heavy-duty vehicles, including long range coach and off-highway. It can play a part in hybrid-electric vehicles and as a range-extender in mainly-electric vehicles where its low emissions, sleek profile, low vibration levels and high efficiency bring advantages of low noise and increased range over other prime movers. By combining the low emissions characteristics of the engine with the cleanness of electrical power, it promises a new era in hybrid energy delivery.

Marine Applications


 
The Covaxe engine is also well suited to marine applications, especially in fast boats, due to its high efficiency, up to 19% greater range for the same fuel load compared to an equivalent compression-ignition engine. The low profile, quasi-cylindrical package makes it ideal for inboard engines and its high power to weight ratio makes it attractive for outboard engines, where the use of diesel fuel is much safer in the marine environment than petrol.
 

Electrical Power Generation and Auxiliary Power Units


 
compression-ignition generators remain prevalent in standby generators for industry, hospitals, etc., portable generators for large outdoor events, in developing countries with poor infrastructure, in disaster relief scenarios, and in auxiliary power units in military applications. The much reduced fuel consumption, low emissions and low weight characteristics of the Covaxe engine makes in an ideal genset prime mover. With a move towards more distributed micro-generation in developed economies, the engine could also form the core of domestic-scale combined heat and power units.

Aviation


 
The engine is particularly suited to aviation installations as a new generation piston engine for general aviation, in both fixed wing and rotary wing aircraft. Aviation gasoline fuel (Avgas) is both expensive and polluting. For this reason several compression-ignition engines, which can run from aviation turbine fuel (Avtur), available at the majority of airports, have entered the European general aviation engine market in the last few years. However, because they have largely emerged from an automotive compression-ignition engine pedigree, they have tended to be heavy, expensive and complex relative to Avgas engines.

The simplicity, light weight, cylindrical space envelope (low frontal area), smooth torque cycle (important for propellers) and significantly increased endurance offered by the low specific fuel consumption, makes Covaxe very attractive for general aviation.

The Covaxe low vibration and use of Avtur also make it attractive for unmanned air vehicles; sophisticated sensors and electronics carried on such vehicles require a low vibration platform.

Finally, the engine could make a good substitute for small turboprop engines and gas turbine APUs, due its much higher thermal efficiency than gas turbines.
