When the all-new Jazz launches later this calendar year it will generate advanced Honda hybrid innovation from the race keep track of to the road. Applying engineering expertise from its motorsport team, Honda is drawing knowledge from its System 1™ Hybrid Electricity Unit (PU) programme to strengthen the electrical power efficiency of the brand’s e:HEV hybrid technique.
The most recent Honda System 1 Hybrid Electricity Unit, named RA620H, employs a highly effective 1600cc six-cylinder inside combustion motor, blended with an Electrical power Restoration Method. The advanced hybrid electrical programs ingeniously recycle electrical power developed by the brakes and exhaust gases to produce more increase electrical power for acceleration and to lower turbo lag. Final year, Honda’s Hybrid Electricity Unit served its lover teams, Aston Martin Crimson Bull Racing and Scuderia Toro Rosso (now regarded as Scuderia AlphaTauri), obtain a complete of three race wins and six podium areas.
All through races, Honda System 1 engineers are continuously evaluating and transforming the ratio of electrical power recovered and deployed by the hybrid technique to supply optimum functionality. The expertise they have developed in functioning hybrid electrical power units at optimum efficiency and electrical power output conjures up Honda’s range of advanced e:HEV powertrains in its passenger cars and trucks.
The most recent road-going beneficiary of this engineering is the all-new Jazz. Its e:HEV hybrid technique recycles electrical power and harnesses it to demand the battery and guidance motor output, for strong functionality, seamless switching in between generate modes and highest efficiency.
Yasuaki Asaki, Head of PU Improvement points out: “All through a System 1 race weekend teams have to handle really meticulously how considerably gas they use to comply with the sport’s regulations. In a race we can divide the complete gas allowance about the quantity of laps, but there are going to be conditions wherever a team could desire to use additional gas in get to get increased functionality and in other areas of the race they will want to save gas for later, though powering a safety auto for instance. In a race, the interaction in between the race engineer and the driver is key to reaching that best equilibrium. Even so, in our road-going e:HEV hybrids we apply our expertise to be certain the Powertrain management units supply the best probable electrical power to efficiency ratio for the driver, in any demanded driving manner.”
The e:HEV technique is newly developed for Jazz and engineered to supply optimum gas efficiency and an pleasurable driving expertise. It consists of two compact, potent electric powered motors linked to a 1.5-litre DOHC i-VTEC petrol motor, a lithium-ion battery and an revolutionary preset-equipment transmission via an intelligent electrical power management device, which all perform harmoniously together to supply a clean and direct reaction.
To supply this sort of a highly-rewarding driving expertise and outstanding efficiency, the advanced e:HEV hybrid established-up seamlessly selects from three interchangeable generate modes:
- EV Travel: the lithium-ion battery supplies electrical power to the electric powered propulsion motor specifically
- Hybrid Travel: the motor supplies electrical power to the electric powered generator motor, which in convert supplies it to the electric powered propulsion motor
- Motor Travel: the petrol motor is linked specifically to the wheels via a lock-up clutch and driveforce is transmitted specifically from motor to the wheels
In most urban driving conditions, optimum efficiency is achieved via seamless transitions in between EV Travel and Hybrid Travel. For driving at highway speeds, Motor Travel is utilized, supplemented by an on-need peak electrical power ‘boost’ from the electric powered propulsion motor for quickly acceleration. In Hybrid Travel, excessive electrical power from the petrol motor can also be diverted to recharge the battery via the generator motor. EV Travel is also engaged when the auto is decelerating, harvesting electrical power via regenerative braking to recharge the battery.
Rather than making use of a common transmission, Jazz is equipped with a newly-developed Electronically Controlled Consistently Variable Transmission (eCVT) with a single preset-equipment ratio to generate a direct relationship in between going factors. The final result is a clean and reassuring transfer of torque with a linear experience all through acceleration across all generate modes.
Honda’s racing heritage dates again to 1958 and in 1965 the manufacturer noticed its initial System 1 acquire. In the course of its participation in System 1, Honda has won a complete of 74 Grands Prix and six constructors titles. This participation in the highest level of motorsport has enabled Honda to manage its highly advanced engineering capabilities and apply its on-keep track of expertise to the road.
