Recently, the China Engine Industry Association and the China Automotive News jointly launched the 2011 “Engine of the Year†awards ceremony held in Beijing. This selection activity has evaluated a total of six categories and 19 award-winning products.
It is reported that CA6DM (heavy duty diesel engine) of FAW Jiefang Wuxi Diesel Engine Factory , JE4D28A (light diesel engine) of Jiangxi Wolff Engine, D19TCI (Passenger Diesel Engine) of Kunming Remo Power, and DAM13R (Micro Gasoline Engine) of Harbin Dongan Automotive Power were obtained 2011 "Engine of the Year" award; Weichai Power's WP12.460E40 and other 15 engine products won the "Energy-saving Engine of the Year", "Environmental Protection Engine of the Year", "Engine of the Year", "Engineering of the Year", and "Year of the Year" respectively. Market potential engine" award.
It is understood that the indicators of the award-winning company's engine products have reached the current level of more advanced, such as the annual engine award of Harbin Dongan Automotive Power DAM13R1.3 litre four-valve DOHC four standard naturally aspirated VVT gasoline engine, or power has been Up to 56.2 kilowatts;
The Europaid OED483Q 2.0-liter four-valve four-country standard common-rail supercharged and intercooled diesel engine with the annual market potential award has a power of 55.3 kilowatts; the Great Wall Motors GW4G15T 1.5-liter four-valve DOHC four-nation standard that received the annual market potential award Turbocharged VVT Gasoline engine with a power up to 65 kilowatts.

Slow-wire cutting processing, also known as slow wire electrical discharge machining (SWEDM), is a precise machining technique used to cut intricate shapes and contours in conductive materials. The process involves using a thin, metallic wire that is continuously fed through a workpiece while an electrical discharge is passed between the wire and the workpiece. This electrical discharge erodes the material, allowing for accurate and precise cutting.
Unlike traditional machining methods, slow wire cutting processing does not involve direct contact between the cutting tool and the workpiece. Instead, a small gap is maintained between the wire and the workpiece, typically filled with a dielectric fluid that acts as a coolant and electrically insulating medium.
The wire used in slow-wire cutting processing is typically made of brass or other conductive materials. The wire is continuously fed through the workpiece in a controlled manner, guided by computer numerical control (CNC) systems. As the wire passes through the workpiece, an electrical discharge is generated between the wire and the workpiece, creating small craters in the material.
Slow-wire cutting processing offers several advantages over traditional machining methods. It allows for precision cutting of complex shapes and contours, even in hard and brittle materials. The process is capable of achieving high cutting speeds and does not create thermal distortion or burrs on the workpiece. Furthermore, slow-wire cutting processing is a non-contact method, which reduces tool wear and prolongs the lifespan of the wire.
