Turbochargers Add Power to
Four-Stroke Recreational Equipment
Turbocharged equipment requires
top-of-the-line lubrication to keep wear in check and increase engine life.
Four-strike recreational equipment has
steadily grown in popularity over the last few years, and the search for
increased power and speed is in full swing. With Honda introducing the first
turbocharged personal watercraft in 2002, and Polaris responding with its own
model shortly thereafter, the race to develop the most powerful four-stroke jet
ski is on.
According to Watercraft World, a
turbocharger boosts power by increasing the levels of air and fuel allowed into
the engine. It includes two turbines, in separate housings but on the same
shaft. Hot exhaust gases travel through one side of the turbine, spinning it.
The vanes on the other side draw and compress air before sending it to the
engine intake. Adjusting housing and vane size allows boost to be controlled.
Turbochargers can be designed to produce extra
boost, utilizing a waste gate to limit boost to the desired level throughout the
motor's rpm range. The waste gate bleeds off excessive pressure, with the
engine's management system controlling it electronically. More power is then
available at lower engine speeds.
Air density decreases at high elevations. In
fact, for every 1000-foot increase in elevation, air density is reduced by 4.5
percent, translating into a 4.5 horsepower decrease in a 100-hp engine.
Turbocharger's waste gate allows full pressure in areas of low density, allowing
full power to be unleashed.
Turbochargers are relatively simple units that
provide mounting flexibility. Ideally, the exhaust turbine is mounted close to
the engine's exhaust outlet and the gases are kept as hot as possible in order
to achieve maximum pressure drop across the turbine vanes on the exhaust side.
Cooling the exhaust decreases pressure.
Because a turbocharger's vanes can spin at
speeds exceeding 50,000 rpm, bearings take quite a beating and temperatures can
become extreme. Pressurizing engines often reduces their life expectancy, so
premium quality, clean oil is essential for extending equipment life.
AMSOIL Formula 4-Stroke Synthetic Motor Oil is
ideal for all four-stroke recreational equipment. Its broad 0W-40 viscosity
rating provides superior protection in both hot and cold temperature extremes,
while its shear stability and resistance to vaporization keep engine wear, oil
consumption, friction, heat and emissions to an absolute minimum.
AMSOIL Formula 4-Stroke
Synthetic Motor Oil provides maximum protection in four-stroke recreational
equipment, including jet skis, outboard motors, ATV's, motorcycles and
snowmobiles.
