To achieve accuracy in model development with large scale customer actual data in low cost and limited time usage of telematics system was adopted. Honda’s OBD II diagnostic connecting device Honda Connect was used as transceiver for this telematics system which was used as an accessory in Honda vehicles. Data collected with this device with large sample size and regional diversity across India was used in product development for Honda System. Control system development for BSVI vehicles, Idle start stop hardware specificaton selection and Battery electric vehicle target range study was done with Honda Connect Data.

Development of High-performance Diesel Engine Compliant with Euro-V

Honda R&D Co., Ltd. Automobile R&D Center-Ryuta Matsui, Kazuaki Shimoyama, Shigeji Nonaka, Isao Chiba, Shoshi Hidaka
Published 2008-04-14 by SAE International in United States
Honda has newly developed a 2.2 L 4-cylinder turbocharged diesel engine that has achieved high power and lower exhaust gas emissions. This engine is a second generation diesel engine, following the first diesel engine for vehicles at Honda, which was launched in 2004. This engine has realized large reductions in exhaust emissions, to allow compliance with EURO-V standards, and enhancements in output and NV performance. To enhance low exhaust emission performance, this engine adopted a 180 MPa common-rail system and optimized the shape of the combustion-chamber. Moreover, to enhance control accuracy under steady state and transient conditions, a Universal Exhaust Gas Oxygen (UEGO) sensor system was applied, and an electric-controlled EGR valve and electric swirl control valve newly developed. In order to enhance output, a newly developed highly efficient variable nozzle turbine (VNT) was adopted, and intake and exhaust system performance have been enhanced. The maximum power and maximum torque of this engine have been increased to 132 kW/380 Nm from 103 kW/340 Nm, compared to the previous model engine. NV performance is a vital…

  • Technical Paper

Published 2005-09-28 by Society of Automotive Engineers of Japan in Japan
Honda has developed diesel particulate filter (DPF) system. Optimization of the multi-fuel injection system, which is able to inject up to four times per cycle, and control of the temperature of the DPF via the use of a variable geometry turbocharger (VGT) and intake control by means of the throttle valve has resulted in reliable DPF regeneration performance. In addition, by improving the accuracy of estimation of accumulated PM mass and reducing fuel dilution of oil, the robustness of DPF system is advanced.
