International Tractors – other nonroad diesel engines: three- and four-cylinder CTD/CTE/CTI-series units from 35 to 54 kW, wastegate turbo, model years 2025/2026
International Tractors Limited, known in India under the Sonalika brand, is a tractor maker based in Hoshiarpur in the state of Punjab and one of the country's largest tractor producers. This page gathers engines of the 3105 and 4105 series that the register could not assign to a named series: 3105CTD, 3105CTE and 3105CTI as three-cylinder units, and 4105CTD as a four-cylinder version.

The register lists here 4 versions with 35 to 54 kW rated output at a constant 2,000 rpm, with three to four cylinders, each with 105 mm bore and 118 mm stroke, all with a wastegate turbocharger and direct injection. The fuel entered is ultra-low-sulphur diesel, the emission level is Tier 4 (Final or Phase-in), the model years are 2025 and 2026. Maximum torque runs from 203 to 335 Nm at 1,400 rpm.
Engines of this power class between 35 and 54 kW power compact to medium farm tractors at Sonalika, with which the company, alongside its home Indian market, increasingly exports to Europe and North America, appearing there as a low-cost alternative to established tractor brands.
On a used example of these recent turbodiesel engines, what matters is the condition of the charge-air cooler, the tightness of the common-rail lines, the function of the exhaust after-treatment and the service history through authorised dealers. Spare parts run through the Sonalika dealer network.
