Volvo North America, Greensboro, N.C., says that, by the fourth quarter of 2002, Volvo-powered trucks will be equipped with the company’s V-Pulse technology, which uses EGR to meet EPA’s new standards.
V-Pulse technology uses pressure pulses created by the exhaust stroke to recirculate up to 30 percent of the exhaust through V-Pulse cooler and back into the air inlet. By using high-pressure, modulating unit injectors, very clean and efficient combustion is reportedly achieved.
Volvo adds that V-Pulse requires only minimal changes in maintenance procedures and technical education. The system will be supported by the company’s PRISM program, which provides drivers, managers and technicians with diagnostic and repair support for Volvo electronics.
