Combining these two systems results in impressive horsepower and high torque with good fuel economy and low exhaust emissions.
• Aluminum block with cast-in iron liners for light weight and durability
• 16-valve DOHC i-VTEC "intelligent" valve-control system
• Lightweight alloy pistons and forged steel connecting rods (11.0:1 Compression Ratio)
• One-piece crankshaft carrier with ferrous main bearing caps for improved rigidity and durability
• High performance camshafts
• Performance-tuned intake manifold
• Drive-by-wire throttle control
• Computer-controlled Programmed Fuel Injection (PGM-FI)
• Direct Ignition System
• Chain-driven balancer unit mounted in oil pan
• Torque rod engine mount system consists of an upper and lower torque rod, a hydraulic body mount and a front beam stopper
• Maintenance Minder system
• Maintenance-free silent-chain camshaft drive
• Maintenance-free serpentine accessory drive with auto tensioner
They gave the common "coil-on-plug" ignition a decpetive "i-VTEC direct ignition" name? Sneaky sneaky! The uneducated person will confuse "direct ignition" with "direct injection". I wonder how much they paid the marketing psychologist team to come up with this stuff? I don't respect companies that spend resources to deceive the hands that feed them. Everything in this list has been done before, even since 1991 like the the one-piece iron crank main carrier cast into an aluminum block, the cast iron liners, the not-listed split block, ECM controlled fuel injection (lol, I can't believe they listed this), lightweight recip. assy. and plain ol' COIL ON PLUG ignition. The only 'unique' feature is the dual lift VTEC and probably the Maint.Minder system, and many cars have this and VVT/VVL is no longer uncommon. Sorry about the rant, I just hate marketing deception and unfounded hype!
