New Approach to ISG from Mitsubishi Electric
Mitsubishi Electric has put the crankshaft-mounted integrated starter-generator (ISG) that it has developed into mass production. The ISG, which is for use in 48-volt hybrid systems, is said to be more efficient than belt-driven starter-generators as it can produce higher output and generate more power, which contributes to fuel efficiency.
When a belt is used to transfer power from the motor to the engine, there is a limitation of the torque and so the peak power output.
By having a direct connection of the motor to the crankshaft, there are overall improvements in the motor’s output power and power generation.
The company has developed a proprietary coil-winding technology that allows a high-density configuration for its motor; this results in a thin-profile that allows the motor to be deployed in various vehicle layouts. (The first production application for this ISG will be in Mercedes hybrids.)
In addition to which, they’ve developed a compact inverter that is characterized by reduced heat resistance and improved durability.
The thing about the Wrangler Willys Wheeler: It is a toy for a grown-up boy.
A young(ish) guy that I’ve known for a number of years, a man who spent the better part of his career writing for auto buff books and who is a car racer on the side, mentioned to me that his wife has a used Lexus ES Hybrid.
Plenty of interior components are injection molded. But some companies—such as VW—are using a process for trim pieces that both mold a component and cover it in fabric in a single molding process. And it is coming to the U.S. in the not-too-distant future.
