MAHLE to showcase scalable and modular hybrid drive concept

MAHLE Powertrain is to showcase its fully integrated and modular hybrid drive in a dedicated MOBEX webinar launching this week.

The MAHLE modular hybrid powertrain (MHP), plug-in hybrid drive that incorporates a highly efficient two or three cylinder turbocharged gasoline engine featuring the latest MAHLE technologies.

It offers several advantages over established hybrid technologies, including cost-efficiency, compactness and reduced weight.

David Pates, MAHLE Powertrain’s UK head of engineering said: “Due to legislation and significant social economic changes the move towards electrification has accelerated significantly.

“The overwhelming industry interest in MHP proves that we have delivered an industry solution at exactly the right time.

“With the EU’s legislated target of 59.4 g/km for fleet average CO2 emissions by 2030, vehicle manufacturers need dynamic technology development and implementation.”

Dedicated hybrid engine

MAHLE Powertrain’s MHP design ensures that the performance of the electric powertrain reduces the demands placed upon the combustion engine, enabling the development of a cost-optimised dedicated hybrid engine (DHE).

The engine concept was designed exclusively for hybrid applications and employs port fuel injection (PFI), a single overhead camshaft (SOHC) without variable valve timing control, and simple two-valve per-cylinder technology to optimise costs.

“The leading feature of the MHP concept is that the engine performance and number of transmission ratios can be optimised using common building blocks, to enable charge sustaining operation for a wide array of vehicles and performance levels” says Pates.

“We believe this will avoid costly investment in sub-optimally specified components that damage efficiency and extend development times. We have worked hard to ensure that MHP offers a strong blend of efficiency and performance without compromising driving pleasure or vehicle range.”

MAHLE jet ignition system

In addition, the MHP engine benefits from the latest innovations made with the passive MAHLE jet ignition (MJI) system.

MJI has been designed to increase ignition energy available in the main combustion chamber through use of a small pre-chamber.

This generates hot ignition jets, which result in more efficient, stable combustion within the cylinder, enabling a safe increase in compression ratio and a highly dilute mixture, through the use of air or exhaust gas recirculation, to help reduce fuel consumption.

MAHLE Powertrain’s testing has shown an increase of up to 20 per cent in thermal efficiency with active MJI compared to baseline modern engines.

MAHLE Powertrain’s MOBEX webinar “Achieving future CO2 targets and maximising commonality with a modular approach to hybridisation” will take place at 10am GMT on 9th June.

Automotive World’s MOBEX, denoting Mobility Explained, is an on-line platform launched in March this year, intended to broaden understanding of the future of mobility through a series of free-to-access presentations by the world’s leading experts.
