Honeywell Gas Turbocharger Boosts New Citroen C4L Model in China

SHANGHAI – Aug. 28, 2015 – Honeywell (NYSE:HON), the leading global developer of automotive turbochargers, is supplying  advanced gasoline turbo technology for Citroën’s new C4L sedan, which launched this month in China and has already earned industry recognition for its powertrain performance.

The downsized 1.2-liter 3-cylinder engine package delivers the power (110kW) and torque of most 2.0-litre 4-cylinder naturally aspirated engines, with the additional fuel economy benefits of achieving an impressive 5.4L/100km. This engine platform won the 2015 International Engine of the Year award for the 1-liter to 1.4-liter category, and is available on various PSA Group models (Peugeot 208, 308, Citroen C3, C4, DS3, DS4) including the Peugeot 308S and 408, which were introduced  in China in April.

“Citroen is bringing a new model to the Chinese market with the help of Honeywell technology, which addresses many consumer preferences with its well-recognized C4L family,” said Charles Jin, vice president and general manager of Honeywell Transportation Systems China. “The smaller yet powerful turbo engine is an excellent collaboration between both engineering teams, delivering a no-compromise solution of impressive fuel efficiency and drivability while also reducing emissions for the environment.”

Honeywell helped Citroen optimize a specially designed boosting system for a 3-cylinder engine with the turbocharger kicking in at low engine speeds around 1,000 rpm while spinning at speeds of up to 240,000 revolutions per minute. Honeywell developed an innovative valve for excess air flow that uses a patented single-piece design with a unique sealing interface to deliver a significant reduction in pulsation and vibration to help create best-in-class controllability, durability and performance while reducing noise.

This high output turbo delivers impressive torque at low engine speeds (95 percent of the engine’s torque is available from 1,500 to 3,500 rpm) and good transient response through the entire range of engine speeds virtually eliminating any lag in turbo operation.

“Turbocharged, three-cylinder engines are becoming increasingly popular in the compact car market,” said Craig Balis, chief technology officer of Honeywell Transportation Systems. “The PSA 1.2-liter is a powerhouse that truly blends the best of small engine fuel efficiency and the low end turbo power that reflects the no-compromise benefits of downsized turbos.”

Anticipating China’s needs as the world’s fastest growing turbo market, Honeywell has added additional localized manufacturing, tripling its capacity in China by opening a new turbo plant in Wuhan in 2014.

“China is determined to achieve the 5L/100km fuel efficiency standards by 2020. We expect to see moredownsized vehicles like Citroen’s C4L to be introduced in China, and Honeywell is well prepared to provide innovative turbos to help automakers deliver on both power and gas mileage promises,” said Jin.
