	In 1896, [[Karl Benz]] patented his design for the first internal combustion engine with horizontally opposed pistons. Usually, each pair of corresponding pistons from each [[cylinder bank\|bank of cylinders]] share one [[crank pin]] on the crankshaft, either by master/slave rods or by two ordinary [[connecting rod]]s side by side. Some authorities even regard this as a distinguishing feature of a true Vee engine, and for example divide [[flat engine]]s into [[boxer engine]]s which do not share crank pins in this way, and 180° engines which do. On the other hand, some important [[V-twin engine]] designs have two-pin cranks. However, in German, these engines are all identified as '''boxermotors'''. (that is wrong, the German terminology distinguishes the "true" Boxer and 180° bank angle engines as such)		In 1896, [[Karl Benz]] patented his design for the first internal combustion engine with horizontally opposed pistons.

A '''V engine''', or '''Vee engine''' is a common [[engine configuration|configuration]] for an [[internal combustion engine]]. The [[cylinder (engine)|cylinders]] and [[piston]]s are aligned, in two separate planes or 'banks', so that they appear to be in a '''"V"''' when viewed along the axis of the [[crankshaft]]. The Vee configuration generally reduces the overall engine length, height and weight compared to an equivalent [[straight engine|inline]] configuration.

In 1896, [[Karl Benz]] patented his design for the first internal combustion engine with horizontally opposed pistons. Usually, each pair of corresponding pistons from each [[cylinder bank|bank of cylinders]] share one [[crank pin]] on the crankshaft, either by master/slave rods or by two ordinary [[connecting rod]]s side by side. Some authorities even regard this as a distinguishing feature of a true Vee engine, and for example divide [[flat engine]]s into [[boxer engine]]s which do not share crank pins in this way, and 180° engines which do. On the other hand, some important [[V-twin engine]] designs have two-pin cranks. However, in German, these engines are all identified as '''boxermotors'''. (that is wrong, the German terminology distinguishes the "true" Boxer and 180° bank angle engines as such)

Various cylinder bank angles of Vee are used in different engines; depending on the number of cylinders, there may be angles that work better than others for stability. Very narrow angles of Vee combine some of the advantages of the Vee engine and the [[straight engine]] (primarily in the form of compactness) as well as disadvantages; the concept is an old one pioneered by [[Lancia]], but recently reworked by [[Volkswagen Group]].

Some Vee configurations are well-[[engine balance|balanced]] and smooth, while others are less smoothly running than their equivalent straight counterparts. With an optimal angle, [[V16 engine|V16s]] have even [[firing order]] and exceptional balance. The [[V10 engine|V10]] and [[crossplane]] [[V8 engine]] can be balanced with counterweights on the crankshaft. [[V12 engine|V12s]], being in effect two [[straight-6]] engines married together, always have even firing and exceptional balance regardless of angle. Others, such as the [[V-twin|V2]], [[V4 engine|V4]], [[V6 engine|V6]], [[flatplane]] V8, and V10, show increased vibration and generally require [[balance shaft]]s.

Certain types of Vee engine have been built as inverted engines, most commonly for aircraft. Advantages include better visibility in a single-engined airplane, and lower centre of gravity. Examples include World War II German engines produced by [[Daimler-Benz]] and Jumo.

It is common practice for Vee engines to be described with '''"V''#''"''' notation, where ''#'' is how many cylinders it has:

*[[V4 engine|V4]]
*[[V5 engine|V5]]
*[[V6 engine|V6]]
*[[V8 engine|V8]]
*[[V10 engine|V10]]
*[[V12 engine|V12]]
*[[V16 engine|V16]]
*[[V18 engine|V18]]
