Compression ignition engines, commonly called diesel, have certain significant advantages in many applications. Among these are reduced fuel consumption, lower-cost fuel, and significantly reduced fire hazard. Potentially longer life and greater reliability are also possible.                 

Ordinarily yes. Nivek R&D's propietary technology to reduce maximum cylinder pressures and our patented monoblock construction method all combine to allow us to produce an engine that is actually much lighter than equal HP gasoline engines, much less existing diesels.

Marine diesel engines of this horsepower usually weigh close to 800 lbs! For example, Mercury Marine® diesels of 165 to 220 HP weigh between 1016 and 1161 lbs. Their 5.7L small block gasoline engine weighs 880 lbs. Considering that these engines are inboards a fair estimate would be to subtract 200-300 lbs for transmissions. Our prototype engine weights in at 236 lbs dry and is rated at 200 HP @ 2500 RPM. Not much of a comparision.
 Aviation engines in this range generally weigh 1.5 to 2 lbs per HP. A Lycoming IO-360 weighs between 321 and 343 lbs, depending on model and produces the same 200 HP.

Nivek R&D is committed to developing environmentally responsible engines. Our Freedom brand engines are environmentally friendly in two ways. To start with, our compression ignition engines use up to 25 percent less fuel than comparable gasoline engines, thus conserving valuable petroleum. In addition, we already meet all applicable emissions regulations and are on track to meet the proposed 2006 guidelines.

The advantages of diesel engines are already well-known. In fact, most boats should already have a diesel engine!   The problem has been in two very important areas; weight, and cost. Up until now both the weight and the cost of small diesel engines has been prohibitive for small to midsize boats. Our Freedom brand engines are a direct replacement for gasoline engines and we intend to provide them at a cost that is comparable with existing gasoline engines.
