Fuel pumps are an essential part of diesel powertrains, transferring the fuel from the tank to the injection system. A typical electric pump is more fuel-efficient than those driven directly by the engine; however, Federal-Mogul says the carbon commutator and brushes found in conventional pumps are subject to wear, which is accelerated by high engine vibration and variations in diesel fuel.
Federal-Mogul claims its electrical brushless fuel pump addresses the shortcomings of a conventional fuel pump. With electronic commutation to drive the DC motor, the company’s cost-effective, non-contact technology is said to be more durable than a conventional pump even when mounted directly on the engine. Durability field tests of Federal-Mogul’s electrical brushless pump showed the product can last approximately 20 times longer than a conventional pump. The pump’s efficient electrically-driven design also reduces the load placed on the engine when compared to conventional belt or gear driven pumps, Federal-Mogul says, thereby improving fuel economy and reducing emissions.
Federal-Mogul’s electrical brushless motor’s universal design also provides ease of installation in existing fuel pump packages to replace current brush-style motors. The design enables the product to readily enhance the life of an engine in service and reduce maintenance expenses, the company says.
“Federal-Mogul is creating a new generation of technology-leading, cost-effective and durable fuel pump solutions for its customers,” says Jose Maria Alapont, president and CEO. “The benefits of our electrical brushless fuel pump far exceed the attributes of a conventional device, and our customers are taking notice.
“We expect the industry’s transition to brushless pump motors to accelerate in the coming years, due to customer demand for longer-life fuel pumps that improve fuel economy and reduce emissions. Leading technology and innovation at competitive cost are enablers in the execution of our strategy for sustainable global profitable growth.”
Federal-Mogul is currently supplying its electrical brushless fuel pump to leading global diesel engine and diesel fuel filtration manufacturers. The company also is offering its electrical brushless fuel pumps through its aftermarket channels for on-highway diesel truck applications.
“By leveraging Federal-Mogul’s diesel engine and electronics expertise, we are developing a new generation of more efficient and more durable solutions for commercial vehicles that will result in better productivity and lower operating costs for end users,” says Ramzi Hermiz, senior vice president of vehicle safety and protection. “Our ability to produce effective solutions that directly benefit our customers’ profitability is one of the reasons Federal-Mogul is a key partner for the industrial and transportation sectors.”
