Abstract
A car having: two front wheels; two rear wheels; an internal combustion engine, which is provided with: a plurality of cylinders, where respective pistons slide on the inside, a drive shaft connected to the pistons, a plurality of intake valves and of exhaust valves operated by respective camshafts, and a cylinder head, where the camshafts are arranged; at least one lubrication pump configured to cause a lubricant oil to circulate; and at least one cooling pump configured to cause a coolant liquid to circulate. A camshaft axially projects out of the cylinder head on at least one side, and the lubrication pump is coaxial to the camshaft and is directly connected to the camshaft so as to be caused to rotate by the camshaft.

A car (1) comprising:
- two front wheels (2);
- two rear wheels (4);
- an internal combustion engine (5), which is provided with:
- a plurality of cylinders (18), where respective pistons (19) slide on the inside, a drive shaft (20) connected to the pistons (19), a plurality of intake valves (22) and of exhaust valves (25) operated by respective camshafts (23, 26), and a cylinder head (21), where the camshafts (23, 26) are arranged;
- at least one first lubrication pump (60) configured to cause a lubricant oil to circulate;
- and
- at least one cooling pump (63) configured to cause a coolant liquid to circulate;
- wherein a first camshaft (23) axially projects out of the cylinder head (21) on both sides;
- wherein the first lubrication pump (60) is coaxial to the first camshaft (23) and is directly connected to the first camshaft (23) so as to be caused to rotate by the first camshaft (23);
- and
- wherein the cooling pump (63) is coaxial to the first camshaft (23) on the opposite side relative to the first lubrication pump (60) and is directly connected to the first camshaft (23) so as to be caused to rotate by the camshaft (23).
