KARIYA, Japan — DENSO Corp. has developed a new starter, the Tandem Solenoid (TS) starter, which shaves up to 1.5 seconds off the restart time when restarting the engine, compared to the company’s previous models. DENSO’s new starter, designed specifically for stop/start systems, uses the world’s first mechanism to separately control the forward shift of the pinion gear and the motor rotation, which allows for a quicker restart, according to the company.

“With the new starter, the pinion gear shift and motor rotation can be separately controlled depending on the engine speed, and the engine can restart while it is still rotating. This shortens the waiting time when restarting and allows for a smoother engine feel at start-up,” said Masahiko Miyaki, senior executive director of DENSO’s Electric Systems Business Group.
