Abstract: Provided is an exhaust gas purification equipment for a diesel engine not only capable of highly-efficient elimination of PM, in particular, SOF components or sulfate components, in exhaust gas of a diesel engine using a low-grade fuel equal to or less than fuel oil, but also capable of easy and reliable suppression of emission of environmental pollutants or ecosystem-affecting substances. The exhaust gas purification equipment for a diesel engine using a low-grade fuel equal or less than fuel oil is configured such that an exhaust gas cooler is disposed in an exhaust pipe which communicates with an exhaust manifold of the engine, an electrical precipitation means for eliminating PM mainly including SOF and ISF contained in the exhaust gas is disposed downstream from the exhaust gas cooler, and a branching portion for causing part of the exhaust gas as EGR gas is disposed in the exhaust pipe downstream from the electrical precipitation means, so that the EGR gas is recirculated to intake air of the engine via an EGR pipe which communicates with the branching portion and an EGR valve.
