EK3 D15B dual stage VTEC
The 3-stage VTEC D15B represents the pinnacle of development on the D15B engine. From the same configuration as the previous generation VTEC D15B; 1493cc SOHC PGM-Fi but now with the 3-stage VTEC system; it generates the same 130ps at a higher 7000rpm with a max torque of 14.2kgm at 5300rpm. The amazing thing is that now it also offers an incredible 30km/l mileage ! In the flesh, the 3-stage VTEC D15B is a sleeper. The valve cover does not have any 'VTEC' wording and only the sharp eyed will recognize the engine as VTEC by noting the VTEC switches (yes, two of them) located on top of the intake runners and the high 7200rpm red-line of the tach. The 3-stage VTEC engine runs in 12-valve mode up to around 3000rpm. In this range, running in ideal conditions will activate the 'lean-burn' mode, where air-fuel ratios as high as 20:1 can be used to take advantage of the intake swirl induced by the 12-valve operation. This lean-burn mode is what makes the 30km/l mileage (for constant 60kmh speed) possible. A green 'ECONO' LED lights up on the dash when lean-burn mode is engaged.
From around 3000rpm up to about 6000rpm, the first VTEC actuator switch engages and the previously inactive intake valve now goes into operation. The engine now runs in 16-valve mode behaves just like any of Honda's highly spec'ed 16valve PGM-Fi engines. After 6000rpm the second VTEC actuator switch engages the wild cam/rocker arm pair for the intake valves. This switches the engine into the wild-cam mode where it goes bonkers delivering 130ps at 7000rpm. With the proper driving style, one can actually enjoy mileage as high as 16 or 18km/l in town driving while at the same time frequently indulging in VTEC-inspired sprints to overtake slower vehicles.
