HyBoost demonstrator debuts at LCV2011; 50% by swept volume downsizing with low-cost electrification

Green Car Congress

Together the partners have sought to demonstrate an extremely cost-effective, ultra-efficient gasoline engine in a C-segment passenger car delivering the performance of a baseline 2.0-liter liter model but with significantly reduced real-world and drive cycle CO 2 emissions, and comparable improvements in fuel-economy.

to 2 ratio points and maintain the same knock limit for an additional 3-4% improvement in fuel economy. It avoids pumping work through the turbocharger to improve fuel economy, and by phasing the two cams, the lobes, relative to each other we can actually modulate boost. improvement in fuel economy on an E-class vehicle (e.g.,

Viable exhaust-driven on-board ethanol reforming for improvements in fuel economy and emissions

Green Car Congress

The low-temperature ethanol-reforming pathway, catalyzed by copper-nickel powder catalysts, transforms ethanol into a mixture of H 2 , CO, and CH 4 at temperatures between 300 and 350 °C. High-temperature reformers need to burn a portion of the fuel to maintain their reforming temperatures, thereby generating a fuel-economy penalty.

Hyundai showcasing new downsized turbo engines and 7-speed dual-clutch transmission; i40 48V Hybrid, i30 CNG

Green Car Congress

The new engine comes with an electronically-controlled waste-gate to optimize flow and improve low-end torque and throttle response. It uses a new split-cooling concept to manage different temperatures in the cylinder head and block area. Up to 15 kg of gas can be stored in the tank at 200 bar pressure.
