A cooling control spacer positioned in the water jacket surrounding the cylinders helps control warm-up and operating cylinder liner temperatures to reduce friction. Plateau honing of the cylinder lining further reduces friction between the piston skirts and the cylinder walls by creating an ultra-smooth surface. This 2-stage machining process uses two grinding processes instead of the more conventional single-stage honing process. Plateau honing also enhances the long-term wear characteristics of the engine. Designed with "cavity-shaped" crowns, the 2018 Odyssey pistons help maintain stable combustion and contribute to stratified-charge combustion. Ion-plated piston rings help reduce friction for greater operating efficiency. Heavy-duty steel connecting rods are forged in one piece and then "crack separated" to create a lighter and stronger rod with an optimally fitted bearing cap.
Mollie Slater Honda, 2017-11-04 19:53:48. Multiple grades of high-strength steel are used in the Odyssey body construction to help achieve excellent overall vehicle dynamics, optimize safety performance, reduce weight, and lower noise, vibration and harshness (NVH). The combination of advanced materials and evolved engineering processes save 75 lbs. in unit-body weight compared to the previous-generation Odyssey. The 2018 Honda Odyssey features several unique advancements in body design and materials that significantly improve overall rigidity, while reducing weight. This directly helps improve overall vehicle dynamics, crash safety performance, interior quietness, and long-term durability.
Eve Fitzgerald Honda, 2017-10-19 15:02:35. New on the 2018 Honda Odyssey are center door rails hidden under the rear side glass that replace the visible rails located on the body sides behind the rear doors on the second- through 4th-generation Odyssey. The result is a clean, seamless appearance for the rear body side and no visible side door rails or components. A safety latch prevents the left-hand sliding door from opening when the fuel lid is open. Like the front doors and tailgate, the side doors feature full 360-degree seals to reduce wind and road noise, water and debris from entering the vehicle.
Mollie Slater Honda, 2017-10-19 15:02:29. Compared to conventional halogen headlights, the Odyssey available LED headlights offer some 32.8 feet (10 meters) wider illuminated area on each side - as well as a 26.2 foot (8 meter) longer reach line - when low beams are in use. The width and reach advantages aid drivers in more safely and confidently navigate both straight and winding roads. Odyssey auto-high beam feature further improves safety. All 2018 Odyssey trims feature LED taillights, whose C-shaped design complements the wing-shaped design of the available front LED DRLs and providing a distinctive Odyssey appearance that is easy to spot on the road. The Odyssey EX-L, Touring and Elite trims feature a power tilting and sliding front moonroof with a manual sunshade. To tilt or slide the moonroof, the driver or front passenger needs only to fully press the ceiling-mounted switch once (instead of pressing and holding it for several seconds). The moonroof fully opens or closes automatically. However, if the operator wishes to only partially open or close the moonroof (such as to achieve partial ventilation), a lighter touch yields fully manual control. The moonroof can also tilt to provide ventilation. An auto-reverse feature is built in, helping to mitigate the possibility of a pinched finger or limb. If the moonroof motor ECU detects a threshold level of mechanical resistance, indicating a possible obstruction, the motor will automatically reverse and reopen the moonroof.
Mollie Slater Honda, 2017-10-19 15:02:30. 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.
Millie Lowe Honda, 2017-10-19 15:02:30. 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.
Libby Wade Honda, 2017-10-19 15:02:31. Based on Honda global light truck platform, the 2018 Odyssey body structure has 44-percent greater torsional rigidity than the previous model. High-strength steel comprises 58 percent of the body structure, contributing to both improved stiffness and reduced mass for the unit-body. Stiffening the body with ultra-high-strength steel, hot-stamped steel and adhesives in critical areas likewise directly contribute to reduced noise and vibration, and improved ride and handling. The structural improvements also help reduce mass, directly contributing to increased fuel efficiency.
Mollie Slater Honda, 2017-10-19 15:02:29. For the first time, the new 2018 Odyssey has 1500-megapascal (MPa) ultra-high-strength steel door reinforcement beams and ultra-high-strength front door outer stiffener rings made of 1500-MPa hot-stamped steel. Laser welded and significantly stronger than ordinary steel, the ultra-high-strength steel reinforcements are designed to help better protect occupants in a frontal or side impact. Their increased strength allows the components to be made lighter which also helps reduce overall vehicle weight for improved fuel efficiency.
Niamh Hart Honda, 2017-10-19 15:02:30. 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.
Niamh Hart Honda, 2017-10-19 15:02:29. The new Odyssey makes widespread use of structural adhesives in the unit-body, supplementing structural welds and significantly increasing rigidity without the additional mass of steel components. Structural adhesives are used at the roof edges and around the moonroof opening, in the front floor and cowl area, in the A- and B-pillars, around the front suspension upper mounts, and extensively throughout the rear of the body. Applied before the body panels are welded together, some 147.6 feet of adhesives (32.8 ft. more than in the previous Odyssey generation) account for approximately 3.5 percent of the entire unit-body stiffness.
