Freescale and ElectroJet technology sets the pace in “green performance” during Bonneville Speed Week

Jesse Beeker, a Freescale field application engineer, rode the 150cc Dayun motorcycles (each with an approximate average retail sale price of $600 USD) to four world land speed records in 175cc pushrod motorcycle classes. His highest record speed during the Bonneville Speed Week was 63 miles per hour (mph), setting a benchmark for green performance for small four-stroke motorcycles.

Most carbureted production motorcycles, scooters and motorbikes with four-stroke engines with displacements below 175cc generate approximately 6-8 horsepower and are designed to reach top speeds of up to 55 mph. The Freescale and ElectroJet runs during Speed Week event are among the first attempts in Bonneville history to set speed records in the 175cc pushrod engine class. The speed runs also demonstrated that performance gains with small engines can be achieved with reduced emissions through the application of electronic fuel injection technology.

“We applaud Jesse Beeker and ElectroJet CEO Kyle Schwulst for their record-setting green performance on Dayun motorcycles during Bonneville Speed Week,” said Steve Nelson, global manager of automotive marketing at Freescale Semiconductor. “A typical carbureted motorcycle or scooter on the streets in developing nations can emit up to four times more harmful emissions per mile than a standard automobile. The Dayun motorcycles that ran at Speed Week featured high-performance yet environmentally friendly fuel injection systems designed to clean up emissions for small two- and three-wheel vehicles.”

The ElectroJet fuel injection systems powering the Dayun motorcycles are engineered to provide cost-effective, highly integrated small-engine control. The ElectroJet systems have been certified by Chinese national laboratories to reduce pollution by up to 90 percent while enhancing fuel economy by 12-15 percent and increasing vehicle performance when compared to similar carbureted motorcycle models. A typical ElectroJet fuel injection system adds less than $50 (USD) to the cost of a small motorcycle design, making it a cost-effective solution for green small-engine control.

”The ElectroJet equipped motorcycles are some of the cleanest of their kind, and the results from Bonneville Speed Week show that environmental friendliness does not undermine the opportunity to achieve high performance,” said Kyle Schwulst, ElectroJet CEO. “These motorcycles are clean and efficient and provide an excellent value proposition to customers in emerging markets such as China and India where fuel economy and vehicle performance are key factors for vehicle sales.”

“If you care about clean emissions and fuel economy as much as engine performance, a solution like the ElectroJet fuel injection system with Freescale MCU technology makes perfect sense for small motorcycles and scooters,” added Freescale Application Engineer Jesse Beeker. “Our record-setting Dayun motorcycles had some of the cleanest running engines at Bonneville Speed Week.”

Freescale’s broad portfolios of semiconductor solutions for powertrain management include 16-bit S12 and S12X MCUs, 32-bit Power Architecture® MCUs, highly integrated analog engine control devices and MEMS-based pressure sensors. These Freescale devices are designed to improve the “green performance” of automobiles, as well as a wide range of small engine designs, such as motorcycles, motorbikes, scooters, 3-wheelers, lawn equipment and other gasoline-powered engines through better fuel efficiency and the reduction of harmful exhaust emissions.
