Surrey, British Columbia, Canada – The Pacbrake Company announced today that its new, patented rocker arm engine brake, which offers performance improvements as well as weight, cost and space savings over traditional rocker arm engine brakes, will be used by Zhejiang Kanghe Mechanical Engineering Co. in the development of I4 and I6, 4 and 6 cylinder engines, for BMC Power Motor (BMC).
Performance improvements of up to 10% additional braking horsepower, over conventional compression release engine breaks, were published to the Society of Automotive Engineers (SAE) on April 3, 2018. Weight, cost and space reduction figures are private.
Compression release engine brakes are devices which, when activated, transform an engine from producing power to absorbing power, converting an engine into an air compressor. This allows the vehicle operator to slow or control vehicle speed. Their use is widespread in the heavy-duty diesel transport industry. When attempting to slow the vehicle, heavy hauling results in severe demand on the service brakes, causing overheating and accelerated wear. The power consumption of the engine generated by the compression release brake reduces the demand on service brakes, increasing safety and extending the life of the service brake.
Traditionally, the compression release engine brake is installed as a stand-alone system in the valve train. Often, the engine designer must make many accommodations such as increasing space in the valve train, supplying dedicated oil feed lines and ports, or adding an additional dedicated lobe on the camshaft. High cost and substantial weight increase are typical characteristics of engine brakes for these reasons. Pacbrake’s novel design offers advantages in weight, cost and space savings that are welcomed by the industry and reaffirms Pacbrake’s leadership in the market.
“The combination of Pacbrake’s agility and strengths in product development, paired with Kanghe’s extensive experience in high quality yet economical manufacturing has formed a collaboration able to provide superior customer value,” says Pacbrake President Gabriel Gavril.
