Yes it's the Renault 1870cc engine as found in the 440/460 but with a bit more complexity on the electronics and EGR systems, for example. Also found in the Mitsubishi Carisma. In my experience the engine, while good in the 440/460 is a bit sluggish in the S/V40 until they put the direct injection head on, which yours probably is though I'm not sure on the exact change over year. It's probably the Renault dTi engine which was direct injection but still from a fuel pump which was known for being willing but noisy until the common rail dCi took over.
