Hyundai’s new era hybrid transmission system.
Hyundai Motor Group (HMG) launched its next-generation hybrid powertrain system on the firm’s ‘Subsequent-Gen Hybrid System Tech Day’ in Seoul this week, which it says will energy a brand new era of “industry-leading” hybrid autos for world markets underneath the Hyundai, Kia and Genesis manufacturers – beginning with the not too long ago launched all-new Hyundai Palisade SUV.
South Korea’s main automaker claims its “significantly-enhanced” hybrid system delivers vastly enhanced energy and effectivity in contrast with the earlier system, and is designed to enhance “the driving and possession expertise of future Group merchandise with customer-focused advantages.”
HMG stated the brand new hybrid transmission system comes with two built-in motors that may be paired flexibly with a variety of inner combustion engines (ICE), permitting for optimized efficiency and gasoline effectivity throughout a spread of car courses. Varied electrification-focused applied sciences have additionally been integrated into the brand new hybrid system to boost driving efficiency, refinement and experience consolation, the corporate added.
Dong Hee Han, head of HMG’s Electrified Propulsion Take a look at Heart, confirmed: “We’ve developed an modern new hybrid system that integrates our long-accumulated engine, transmission and hybrid system improvement expertise with the electrification expertise utilized to our world-class electrical autos. We are going to proceed to develop modern applied sciences that actively make the most of electrification capabilities through the transition to EVs, offering clients with eco-friendly autos that supply superior efficiency.”
The brand new hybrid transmission system features a new P1 motor that handles beginning, battery vitality era and vitality deployment to help propulsion. The P2 driving motor is accountable for propulsion and regenerative braking. This built-in dual-motor setup is claimed to enhance energy, efficiency, and fuel-efficiency whereas attaining easy shifting and decreased noise and vibration for a extra refined driving expertise.
HMG confirmed that the brand new hybrid transmission system “might be paired flexibly with ICE engines throughout the group’s lineup, delivering a system output from the low-100 PS vary to the mid-300 PS area and permitting for broad software from sub-compact to giant autos.” The brand new system additionally integrates “comfort options generally discovered within the group’s EVs, comparable to Keep Mode, Car-to-Load (V2L) performance, and Good Regenerative Braking.”
The brand new hybrid transmission system is initially being utilized in mixture with a newly-developed gasoline 2.5-litre turbo engine within the all-new Palisade, to be adopted by a 1.6-litre turbo hybrid powertrain within the new Santa Fe.
HMG identified that “by reassigning the two.5L engine’s beginning and producing duties to the newly added P1 motor, the turbo hybrid powertrain minimizes energy losses. Mixed with enhanced cylinder circulate throughout the new engine and the adoption of a high-efficiency cycle optimized for hybrids, gasoline effectivity has been improved.”
“Sometimes, inner combustion engines generate energy via 4 strokes, whereas the two.5L turbo hybrid system makes use of an ‘over-expansion cycle’, deliberately delaying consumption valve closure throughout compression to decrease the efficient compression ratio of the combined fuel within the cylinder whereas sustaining a excessive enlargement ratio through the combustion course of. This system reduces energy consumption throughout combination compression whereas maximizing vitality generated after combustion, considerably enhancing engine effectivity.”
The gasoline 2.5 turbo hybrid system used within the all-new Palisade, launched earlier this 12 months, delivers most gasoline effectivity of 14.1 Km/litre, a most system output of 334 PS, and most torque of 460 Nm, providing roughly 45% higher gasoline effectivity, a 19% improve in most energy, and a 9% enchancment in most torque.
