Waukesha VHP Series 5

The Waukesha VHP Series Five enriched mixture engines combine innovative technology with 50 years of experience in the VHP engine range. The Series Five family of engines, L7042GSI S5, L7044GSI S5 and P9394GSI S5, delivers 13% more horsepower, increased fuel flexibility, a 10% reduction in fuel consumption, a maximum 20% reduction in life cycle cost and extended service intervals of more than 30%. The increased power and improved performance are retained when temperatures or pressures rise above the values set for VHP models, meaning the Series Five engines operate by applying intelligent features rather than excessive force.

ENHANCED EFFICIENCY

The Series Five engines are capable of delivering more power than previous versions without increasing the load on engine components. This is made possible by combusting an enriched fuel mixture using the Miller cycle, a modified cylinder head design that lowers the temperature in critical areas, and optimised piston design. The Miller cycle, shifts operation from the piston to the turbocharger, reducing combustion and exhaust temperatures, making Series Five engines the most fuel-efficient VHP engines ever, despite running in an enriched fuel mix mode.

ENHANCED DESIGN

Improved cylinder head improves reliability and cylinder head life. The piston design is optimised to reduce the amount of unburned hydrocarbons, improving emissions and fuel consumption while reducing the temperature of the piston itself, and this improves fuel versatility even at high power ratings. Improvements to the ignition system allow the spark plug change interval to be extended to 4,000 hours.

FUEL ECONOMY

A 10% reduction in fuel consumption reduces the carbon footprint and harmful emissions. Engines running on an enriched fuel mix can be more fuel-efficient than those running on a lean mixture. Reduced heat loss allows a similarly sized cooler to be used on larger engines.

Scope of application:

  • Injection into the reservoir
  • Cogeneration
  • Oil and gas
  • Pumping of oil and gas
  • Downstream Processing
  • Recovery of produced gas / Wellhead
  • Storage
  • Energy supply for oilfields
