DENSO Develops Exhaust Gas Temperature Sensor With Improved Temperature Detection Accuracy

Green Car Congress

DENSO Corporation has improved the temperature detection accuracy of its newly developed diesel exhaust temperature sensor. To improve the sensor’s temperature accuracy, DENSO increased the probe length to almost twice that of the conventional product and extended the sensing tip into the exhaust pipe. Click to enlarge.

Pierburg GmbH electric compressor for turbos

Green Car Congress

Pierburg GmbH, part of the KSPG Group, has developed an electric compressor for spontaneously boosting the charge pressure of engines fitted with an exhaust-gas turbocharger. This component allows pressure to be increased regardless of the exhaust-gas energy availability.

Downsized 4.0 TFSI for Audi S8 cuts fuel consumption 23% compared to predecessor; cylinder deactivation and start-stop

Green Car Congress

Audi’s principle of downsizing: “ Forced induction replaces displacement ” One twin-scroll turbocharger per cylinder bank compresses the fresh air. From each pair of cylinders, the exhaust ports lead separately to a manifold and the turbocharger housing; they are not combined until immediately ahead of the turbine.

Federal-Mogul expands powertrain materials portfolio for more efficient heavy-duty diesel engines

Green Car Congress

A heavy-duty exhaust valve guide with thermal deformation and temperature color scaling demonstrates high side load at high temperatures in contact with the exhaust gas. The solid lubricant package, combined with vacuum oil impregnation, delays valve stem scuffing in high temperature, heavily side-loaded applications.

Optimizing a CNG-Fueled Spark Injection Engine for a Parallel Hybrid Powertrain

Green Car Congress

Since the end of 2006, Opel, Robert Bosch, IVK and FKFS have been working on a natural gas hybrid vehicle in a project supported by the German Federal Ministry of Economics and technology. bar) is achieved by applying high- or low-pressure exhaust-gas recirculation loops. By adding an exhaust gas turbocharger to the base 1.0L

MECA report assesses technology feasibility for heavy-duty diesel trucks to meet lower NOx standards by 2024

Green Car Congress

In the latter, CARB staff signaled a plan to align the regulatory provisions for the first phase of NO x tightening with the second implementation stage of the Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles - Phase 2 in 2024. The cost of controlling NO x to 0.05 Credit: MECA.

New Federal-Mogul Powertrain high thermal conductivity seats and guides keep engine valves cooler; improved combustion, lower emissions

Green Car Congress

The extreme valve temperatures experienced on today’s highly boosted downsized engines can lead to reduced valve fatigue life and critical valve guide and stem seal temperatures, resulting in the need for expensive valve steel alloys. A combination of HTC and TIM technologies reduced peak inlet valve head temperatures by between 26 and 32°C.
