This is understandable: unlike, say, the drills at the pump is not idle – it just has to start pumping water. Engine The engine is rightly viewed as 'heart' installation. It was his resource defines the term 'life' power: the average time between failures of an electric power is always several times higher than that of the motor. In most cases, the class of plants is determined used engines or, more precisely, its lifespan. In particular, high-quality gasoline engine uptime before the first failure probability is calculated on average 3-5 thousand hours, whereas the simplified cheap motor – just hundreds. Diesel power, usually have the resources is much higher than petrol, its economical fuel consumption, and self-diesel fuel cheaper than gasoline and can be less stringent conditions for storage, but the power collected at the base diesel engine in 1,5-2 times more expensive than similar in power, but collected at the base gasoline engine.

Therefore, the choice in favor of the plant collected in the the base diesel engine rationally do if: – the use of power as the main source of power (at least in cases of prolonged use it) – the use of a homogeneous species fuel (availability of units operating on diesel fuel) – electric power above 10-12 kVA, which power to gasoline engines practically applied. Distinguish high-quality motor on the outside signs are not always easy. If before the mini-power plants are widely used engines with side valves, it is now very often – the overhead, performance, approximately 30% higher.

Vosper Thorneycroft Engine

As a result of their propulsive performance modern water-jet almost as good as the propeller, and at high speeds and often exceeds it. Water cannon is very popular, where high-speed small craft should move freely in shallow water. Firm 'Vospauer' – a division of the famous British company 'Vosper Thorneycroft', which is building a small patrol boats and military vessels, has developed a series of water jets for advanced landing craft as the only engine of this allows such a vessel on the go 'pop' on the beach, and then weigh it on their own through the back of the jet, which drives the water under the hull. This advantage can be use and pleasure crafts, specially designed for 'landing' on unequipped shelving shore. Perhaps that is why the American company 'Hinckley' water cannon installed on their 36-foot model deykreysera, which by chance is called 'Picnic'. Safety – another positive feature water jet. The impeller is located inside the boat and not a danger to people nearby in the water.

This – the main reason for used water cannons and jet-skiers in tow. Rescue boats – another area where the water jets can play safety critical. In most cases, water-jet boat added solid fraction of the weight. Precise: not so much an engine as being in the water it constantly. When calculating the weight of the propulsion speed vessels of this water must be to add on to the weight of the vessel. Part of this added weight may compensated for the lack of line shafting gear as reverse and 'stop' provides a simple turn of the deflector (but in most plants need at least clutch between the engine and water cannons to the motor can operate independently of an engine operating mode).
