Acoustic laminated windshield glass helps reduce noise entering the cabin on EX-L and above trims. Tuned specifically to attenuate wind-, urban- and traffic-noise frequencies, the acoustic windshield uses an outer layer of 2.0 mm safety glass, a 0.7 mm thick middle layer of acoustic polyvinyl butyral (PVB) and a 2.0 mm inner layer for a total thickness of 4.7 mm - an increase over the 4.5mm thickness of the previous-generation Honda Odyssey windshield. This helps the Odyssey place at the top of its class in wind-noise performance.
Once the engine is fully warmed up, for maximum power and fuel efficiency fuel is injected during the intake stroke. This helps create a more homogeneous fuel/air mix in the cylinder that is aided by the high-tumble intake port design. This improves volumetric efficiency, and the cooling effect of the incoming fuel improves anti-knock performance. Every 2018 Odyssey is equipped with an ECON button that helps improve fuel efficiency by modifying throttle mapping and HVAC operation. When the system is operating, a green ECO indicator appears on the instrument panel and the Drive-by-Wire throttle system provides a more gradual response. To save additional energy, the climate control system characteristics are altered based on the conditions. A green coaching light in the instrument display gives the driver feedback to help improve their real-world fuel economy and instant or average fuel economy can be displayed.
The Odyssey Electronic Control Unit (ECU) monitors engine functions to determine the best ignition spark timing. Two engine block-mounted acoustic detonation/knock sensors "listen" to the engine, and based on this input, the ECU can retard the ignition timing to prevent potentially damaging detonation. The engine has an ignition coil unit for each cylinder positioned within each spark plug access bore. To help improve fuel efficiency, the Odyssey Touring and Elite are equipped with Idle-Stop capability. When the system is enabled by the driver and certain operating conditions are met, the Idle-Stop system will automatically shut off the engine when the vehicle comes to a stop. The engine is automatically restarted when the driver releases the brake pedal after a stop, or if the steering wheel is turned. If the Brake Hold system is in use, the engine quickly restarts after the throttle is depressed.
The Odyssey new engine - from the Honda EarthDreams® Technology powertrain series - is rated at 280 peak horsepower and 262 lb.-ft. peak torque. Peak engine output is up 32 horsepower and 12 pound-feet of torque from the previous model, with increased torque over the engine entire operating (rpm) range. The new, more efficient engine and transmissions, along with as much as a 75-pound reduction in vehicle weight (EX-L trim) and improved aerodynamics, among other reductions to running resistance, result in enhanced performance and fuel efficiency. With its 60-degree V-angle, the Odyssey V6 engine is inherently smooth and has compact overall dimensions that allow efficient packaging within the vehicle. The engine has a high-pressure die-cast lightweight aluminum alloy block with cast-in-place iron cylinder liners. Made with a centrifugal spin-casting process, the thin-wall liners are high in strength and low in porosity. The block incorporates a deep-skirt design with four bolts per bearing cap for rigid crankshaft support and minimized noise and vibration. The engine also uses a high-tensile strength steel crankshaft is for minimum weight.
