Diesel engines in the past tended to emit large amounts of smog-producing fumes because of their high-temperature compression ratios. But, just as in gasoline-powered cars, a technology called variable-valve lift (VVL) helps reduce emissions by optimizing gas use in the cylinder. Until recently, VVL technology for diesels had lengthy development times and thus targeted premium vehicles where the added costs could be more readily absorbed into the sticker price.
