• The prospect of CNG becoming a really viable alternative to diesel as a fuel for LGVs received a boost this week as Lane Group introduced a CNG-fuelled ERF EC truck into its fleet run for The Body Shop. Bristol-based Lane Group already operates a number of heavy trucks on low-sulphur diesel as part of its work for the environmentally active cosmetics company. The EC10 rigid is powered by a version of Cummins-L10 240G spark-ignition CNG bus engine—originally developed to meet California's tough emission laws. The 240hp (179kW) charge-cooled L10-240G has a peak torque of 1,153Nm at 1,400rpm. Like the Scania engine it uses a wastegated turbocharger—but all fuelling is controlled by Cummins' CELECT electronic fuel management system. To reduce emission levels even further the Cummins L10-240G can be equipped with either a catalytic convertor or particulate trap. The CNG engine is basically the same as the 110 diesel but with a leanburn gas system with carburettor, governor and spark ignition; the overhead assembly, which has a jacket water after-cooler has also been revised to allow a 25% higher injection pressure for better fuel atomisation and lower emissions.
The L10-240G has an air/fuel ratio of 26:1 and a reduced compression ratio of 10.5:1.
