On-road emission measurements of 23 VN-trucks on a randomly chosen driving cycle, consisting of 10 miles two-lane and 8 miles four-lane road, showed tailpipe NOx emissions on fleet average of 0.96 g/bhp-hr, or 1.06 g/bhp-hr when including the time the exhaust gas temperature was below 200°C. Complementary measurements in a SET-cycle (13 point OICA -cycle) on a chassis dynamometer showed a tailpipe emission of 0.008 g PM per bhp-hr. Moreover, cost analysis show that the diesel fuel consumption remains unchanged whether the truck running on ULSD is equipped with a Combined Exhaust gas AfterTreatment System (CEATS) installed or not.

Mainly due to environmental regulation, future Engine Control Unit (ECU) will be equipped with in-cylinder pressure sensors. The introduction of this innovative solution has increased the number of involved variables, requiring an unceasing improvement in the modeling approaches and in the computational capabilities of Engine Control Unit (ECU). Hardware in the Loop (HIL) test system therefore has to provide in-cylinder pressure in real time from an adequate model. This paper describes a synthesis of our study targeted to the development of in-cylinder crank angle combustion model excluding look up tables, dedicated to HIL test bench. The main objective of the present paper is a comprehensive analysis of a reduced combustion model, applied to a direct injection Diesel engine at varying engine operating range, including single injection and multi injection strategies.
Engineers who analyze combustion processes do not need more variables. However, biofuels, which have burning and performance characteristics that differ sharply from petrodiesel, will alter the way engines perform.
ETAS launches FlexECU, an open control system development platform to develop, implement, and test new control system concepts on production-intent electronic control unit (ECU) hardware.
Ricardo has developed a spark-ignited V6 engine that matches the performance of a larger V8 diesel engine while also reducing costs. Its Ethanol-Boosted Direct Injection (EBDI) also has the potential to reduce aftertreatment size while letting operators use a range of fuels.
Robert Bosch GmbH, Deutz AG, and Eberspaecher GmbH & Co. KG have signed an agreement to set up a joint venture—to be known as Bosch Emission Systems GmbH & Co. KG and headquartered in Stuttgart—in the area of diesel exhaust aftertreatment.
International Truck recently unveiled its all-new engine for the Class 8 market called the International A26, in addition to a new initiative called Project Alpha, which brought together a small team of powertrain engineers dedicated to a new perspective on engine development.
Bosch has developed a comprehensive connectivity platform that can reduce a vehicle's fuel consumption, foresee when maintenance is needed and display all information on the owner's smartphone. In line with its “in-the-region-for-the-region” strategy, Bosch presented its Intelligent Transport Management System (iTraMS) at the Bosch Technology Exposition 2016 in Noida, India.
Bosch has introduced its highest-output compact off-highway alternator for power, fuel savings, and reliability: the 240-A, 14-V (150-A, 28-V) “P” or Power-feature alternator.
Harnessflex TempGuard conduit and fittings from ABB Electrification Products are designed specifically to protect and route high-temperature cables, providing an integrated system for engine wiring in temperatures up to 392°F (200°C).
Many among the 13 partners that jointly developed the Genius CAB concept are firmly established in the automotive industry, and quite of few of these suppliers note the influence their automotive arms played in their contributions to the project.
In his opening keynote address at SAE COMVEC 17 on Sept. 18, Dr. Johannes-Joerg Rueger, President of Commercial Vehicle and Off-Road at Bosch, noted that SAE Levels 4 and 5 for vehicle autonomy may be more attractive for commercial vehicles because they can help address the driver shortage and reduce operational costs.
Nikola Motor Company named Bosch and PowerCell Sweden AB as primary suppliers in the development of the fuel-cell system for the Nikola Two day-cab Class 8 hydrogen-electric truck targeted for 2021 production.
