|C Gas Plus engine|
These buses will exclusively transport workers to and from the AutoVAZ car manufacturing plant located in Togliatti, Samara region, 1,000 km from Moscow. AutoVAZ is the largest car manufacturer in Russia, and the plant in Togliatti produces more than 700,000 cars annually.
This is the first major order of Cummins Westport natural gas engines by a CIS Original Equipment Manufacturer. The first prototype natural gas engine was delivered to the OEM, LiAZ in 2003. Currently, there are 7 prototype buses of various models which will be operating in a number of Russian cities.—Alexei Ustinov, Cummins Russia ABO Head
This marks one of the largest orders for Cummins Westport, and the largest yet in Europe.
Russian Buses is the largest manufacturer of buses in Russia. It manufactures buses under the LiAZ, PAZ, GoIAZ and KAVZ brand names. It is a division of RusAutoProm, a conglomerate whose businesses are engaged in manufacturing of buses, small and large trucks, cars, road-construction equipment, loaders, diesel and gasoline engines, and fuel instrumentation.
The C Gas Plus engines are certified to Euro-3 standards.
Separately, Westport Innovations announced that it has received California Air Resources Board (CARB) Certification for its High Pressure Direct Injection (HPDI) LNG technology (earlier post) adapted to the Cummins ISX heavy-duty truck engine.
The Executive Order from CARB certifies the HPDI system to 1.2g/bhp-hr [NOx + NMHC] and 0.02g/bhp-hr Particulate Matter (PM).
CARB certification represents the major milestone required for us to make the heavy duty Cummins ISX HPDI LNG (liquefied natural gas) engine and fuel system available to commercial fleets in California for deployment in 2006.—Michael Gallagher, President & Chief Operating Officer of Westport
The ISX HPDI engine will be offered in two ratings, 400 horsepower with 1,450ft-lbs torque, or 450 horsepower with 1,650 ft-lbs torque, matching the diesel-fueled base ISX engine.
HPDI allows a diesel engine to operate with over 90% replacement of diesel fuel by natural gas. By directly injecting the natural gas at high pressure in the engine, HPDI reproduces key benefits of diesel engines: high efficiency over the speed and torque operating range, high torque capability and robust reliability.
The use of pilot diesel provides powerful ignition and contributes to the reliability and durability of the system. At the same time, the properties of natural gas contribute to a significant reduction in combustion by-products: nitrogen oxides, particulate matter and greenhouse gases are all significantly reduced as the engine operates under the same performance as the base diesel engine.
