The article says the laser improves combustion efficiency by 27%. That's only possible if the engine is currently leaving ~27% of the fuel unburned. If that was the case it wouldn't meet any sort of smog regs. The current engines burn very cleanly, which means they burn nearly all the fuel, which means there isn't really much to gain by burning it even better.
