A Task Scheduler engine performs the actions scheduled through the Task Scheduler. A Task Scheduler engine communicates with the Task Scheduler service to execute tasks. The service creates a task engine to run tasks.

“A task engine starts when a task is run for a specified principal (the security context the task runs under). The Task Scheduler engine manages a queue of tasks that are scheduled to run. A task is put in the queue when the service determines the task should run. The queue has a quota that defines the number of tasks allowed in the queue. The quota is defined in a registry key value. The Task Scheduler service enables you to perform automated tasks on a computer. With this service, you can schedule any program to run at any time or when a specific event occurs. The Task Scheduler monitors the time or event criteria that you choose and then executes the task when those criteria are met.”
