Head and Valvetrain Specs J35A3
The Honda J35A3 engine is equipped with an aluminum alloy head and a VTEC (Variable Valve Timing and Lift Electronic Control) valvetrain. This type of valvetrain allows for improved engine breathing and increased power output.
The VTEC system works by changing the lift and duration of the engine’s valves, depending on engine speed. At lower speeds, the engine uses small, low-lift cam profiles, which provides improved fuel efficiency and reduced emissions.
At higher speeds, the VTEC system switches to high-lift, high-duration cam profiles, which allows for maximum airflow into the engine and improved power output.
The aluminum alloy head provides lighter weight and improved heat dissipation compared to cast iron heads, allowing for improved engine performance and efficiency.
Additionally, the head is designed with specific shapes and contours to optimize airflow into the engine and improve engine breathing.
Together, the VTEC valvetrain and aluminum alloy head provide improved engine performance, fuel efficiency, and emissions compared to conventional valvetrains and heads.
The Technologies Used in
The Honda J35A3 engine uses two key technologies: VTEC (Variable Valve Timing and Lift Electronic Control) and Variable Cylinder Management (VCM).
1. Vtec
VTEC (Variable Valve Timing and Lift Electronic Control) is a valvetrain system that allows for improved engine breathing and increased power output. The VTEC system works by changing the lift and duration of the engine’s valves, depending on engine speed.
At lower speeds, the engine uses small, low-lift cam profiles, which provides improved fuel efficiency and reduced emissions. At higher speeds, the VTEC system switches to high-lift, high-duration cam profiles, which allows for maximum airflow into the engine and improved power output.
2. Variable Cylinder Management (Vcm)
VCM is a cylinder management system that allows the engine to switch between using all cylinders and using fewer cylinders, depending on driving conditions.
During low-load conditions, such as highway cruising, the engine switches to a 3-cylinder mode, which provides improved fuel efficiency. During high-load conditions, such as accelerating or towing, the engine switches back to a 6-cylinder mode, providing improved performance.
This technology allows for a tradeoff between improved fuel efficiency and improved performance, depending on driving conditions.
Together, VTEC and VCM provide improved engine performance, fuel efficiency, and emissions compared to conventional engines.
Performance Review
The Honda J35A3 engine is a powerful and efficient powerplant, delivering impressive performance and fuel efficiency.
With a displacement of 3.5 liters and an output of 240 horsepower and 242 lb-ft of torque, the J35A3 provides strong acceleration and passing power.
The VTEC valvetrain and aluminum alloy head provide improved engine breathing and power output, and the VCM system allows for a tradeoff between improved fuel efficiency and improved performance, depending on driving conditions.
In terms of fuel efficiency, the J35A3 engine provides impressive numbers, thanks in part to its VTEC system and VCM technology. During highway cruising, the engine operates in 3-cylinder mode, reducing fuel consumption and improving fuel efficiency.
Overall, the Honda J35A3 engine provides a well-rounded package of performance and efficiency, making it a great choice for those who want a powerful and efficient engine in their vehicle.
Whether you’re looking for a vehicle to use for daily commuting or weekend road trips, the J35A3 engine provides a solid foundation for a great driving experience.
